What? This makes no sense. Attackers would lose every single match if they just sat outside and tried to pick people off.
I didn't say that. I said there was no risk to them yet there's high reward. For instance Glaz sitting on the treehouse on House has no significant risk, yet the spot offers very high reward (control over the main second floor corridor, restricting enemy movement and nabbing easy kills with his low contrast scope.
Without the ability for a player to step outside and threaten or kill him, there's no realistic way to suppress a good Glaz player here. Stepping into the corridor that he is already pre-aimed on is suicide against anyone that isn't terrible, therefore having the option to use the basement doorway to step out and get sight on the front of the treehouse and window actually balanced out that encounter.
Just doesn't seem like a very interesting mechanic if people can just sit and probe the inside of the house with no risk to themselves. Obviously it's easier for attackers to win those encounters, they have assault and marksman rifles, so the only thing that meditates the efficacy of such external probing strategies is the potential to be flanked and killed.
At the same time, any successful flank requires careful planning and coordination with allies, on the topic of the enemies location. Running outside the building by itself, typically yields nothing. You have to have a route in mind, you have that route secured and you have to be incredibly fast to pull any of it off.
Really feel like something got lost in translation here. I said I wouldn't mind if defenders couldn't go outside--what you're describing is an attacker scenario. It's completely fine for the attackers to go outside, obviously.
Sorry if I wasn't clear. I was talking about how the defender would literally need to go outside in order to deal with this scenario, else the round is lost. If the attacker is rappeling a window after a bomb plant in a 1 vs 1 scenario, they have absolutely no incentive to expose themselves until they hear you hitting the bomb, at which point you're at a lose lose scenario, you either hit the bomb and die, or leave the bomb and wait for him at a window that he never pokes.
The only answer here against a good player is to risk a quick outdoor flank. Sure, at this stage you've already gotten yourself into a bad scenario, but you definitely should have options.
This is just flat out untrue. There are plenty of flanking opportunities from within the structures, not to mention how dynamic the destruction can make the game inside.
EDIT: And let's be real--restricting the ability for defenders to roam outside the house/structure would have very little impact on the game's balance. Seriously, how many rounds/matches has going outside decided for you? Out of the ~240 matches I've played, roaming as a defender has decided maybe...five? Six?
It's a nuisance that's unnecessary--it's not integral to the gameplay or balance.
Well, it's not untrue, because I didn't say that there were no flanking opportunities from inside the building, and I provided one instance where there are none, without an outdoor flank. The garage breach has the one entry point, so flanking it isn't possible without going outdoors.
As for the frequency, I guess it's a playstyle thing, but depending on the map, I will be stepping outside the building on a very regular basis. On Clubhouse I will use the outside to move across the two second floor buildings and pincer the enemy team, on house I will use the outside to flank the garage, on Canal I will take shots as they leave spawn and then relocate to flank their adjusted location, using the opposing buildings upper floor as an out-door flank / kill opportunity. On Kafe I will hop outside the windows to kill enemies approaching the door. on Shallet I will flank the garage. I might hop outside the window ledges to kill enemies at the backyard door too. On plane I'll pop outside to figure out where they are attacking from, perhaps take a few potshots. I don't always do it, it depends on the team, the round we're in, and what I've done on the rounds before.
Every time I play or see ranked games against gold and platinum teams, I see this component as a very prevalent strategy. Certainly in the average, casual lobby it probably doesn't make a difference. But nothing does. Like I said on my reddit post on the same topic, the guys in the GIF I posted were bad. They would have been killed whether they died on the stairway or inside the plane.
But I mean, just because you don't see it often in casual lobbies doesn't mean it isn't effective and influential. I would say outdoor roaming is heavily integrated into my teams playstyle and influential to the win in about 1/3 or 1/2 of the defensive rounds I have played. The reason you see influencing the match less, is probably because you do not do it often yourself. Typical players do not.
I also think it's really easy to look at these manuevers on the outside and suggest they are cheap, but in the end, I think that really underappreciates the tactical coordination required to successfully pull them off. If you are going to do an outdoor flank you get one shot at it. You can't poke out then do it again because if you're marked you're covers blown, they know where you'll be, so you need to know where your opponent is, what he's doing, what he is (weapons etc) and his general preparedness for the strategy. If I hop up the stairwell on Canal to kill Glaz, I need to know where he is, and he needs to be unaware of me. That requires him to be relatively immobile and predictable, possibly to have forgotten to take the cameras out (often the case) and oblivious to my position. It's much harder, and far more contingent on my opponents being negligent, than you make it out to be.
Another point is, that while it may not be present in every round that perspective reflect degree of naïveté on this games dynamics. Siege offers a myriad of avenues of approach and strategy for each individual map, and the strategies, routes, windows, doors, breaches, ceilings that aren't used, are in many ways just as significant and influential on the gameplay as the ones that are. To iterate, let's say I kill one player by hopping outside the lower doorway on house on the first round. From now on, Glaz isn't going to feel safe in the tree house. Neither him, or anyone rappelling the window is going to need to carefully adapt their gameplay to accommodate the possibility that they might be approached from another avenue of attack.
Against good teams it doesn't require them to be killed in that way, to become wary of the potency of such a strategy, accommodate that into their gameplay strategies at a very fundamental level. This makes for more cautious, tactical outdoor gameplay where attackers have to place consideration on potential flanks, and encouraging teamplay and a generally more mindful approach, where allies have to cover one another as they enter the building. Even when these strategies are not explicitly employed within a match, it's very easy to see how they affect the gameplay dynamics at a very fundamental level.
Defenders roaming about outside is generally cheap.
That is all.
How is it cheap though? It's harder for him to pull off, than it is for you to deal with it. It's absolutely contingent on the defending team making a mistake or oversight. If there were nothing you could do to accommodate it, I would understand that perspective.
It feels akin to saying something like anti-airs are cheap on Street Fighter. Please, just stop jumping. It's easier for people to blame external factors (the game or other players), than it is for them to reconsider their own behavior (adapt).
