Spent yesterday going through and trying out every weapon. Seems that balance is a little odd in this game. I want to go through that quickly and see if what I think aligns with the perceptions of others
Assault rifles
The default is probably the best gun in the game, tight spread, good time to kill and incredibly versatile. It's a great weapon capable of going head to head with many of the SMGs, while keeping you effective at mid range combat. The fourth assault rifle is decent enough but the erratic spread is more likely to let you down.
The rest all serve their own, albeit circumscribed purpose. The burst can be quite devastating when combined with amped damage, causing one burst kills become the norm rather than the exception, even at mid-long ranges.
SMGs
The CAR is decent enough, faster TTK than fully automatic assault rifles or light machine guns, yet struggles at range. The rest are more of the same, both the R97 and Alternator sacrifice accuracy for a slightly faster time to kill than the CAR, but that has its own drawback, ultimately the CAR is the go-to here.
The Volt is in a really awkward spot with the slowest time to kill, arguably compensated with its enhanced accuracy when compared to the others. The issue here is that you'd generally be better off using the G2A5 assault rifle instead, as it more capably handles that mid-long range and performs similarly to the Volt when up close.
LMGs
The Spitfire and Devotion are good enough. Lower time to kills than most assault rifles but they can get kills at further ranges than the G2. They're good options if you want a fully automatic that can cut it a little better at those mid-long ranges but suffer up close. Generally I wouldn't favour them over the assault rifles. The L-Star seems especially bad.
Grenadier
Entirely useless category of weapons. The softball is the best of the bunch if you really must use one since if the grenade hits the target it kills them, but that aside the rest of them are woefully weak. Great way to get pistol kills if you use those as these grenadier weapons often leave targets at low hp, forcing you to switch to a secondary or die. As anti titan weapons they're just worse than the existing anti-titan weapons. Honestly I think it would be worth moving them to the anti-titan category and buffing their damage in that area, as I don't see much benefit of these in the primary slot for which they would need to be much more effective.
Shotguns
Generally I wouldn't recommend these since the TTK is so low on every gun and you lose so much versatility by using something that's strictly close range only. However the Masstifs pump action can let you down and given the mobility of pilots in this game it's easy for enemies to stray out of your effective range, causing you to die if you don't get the one-shot kill.
Snipers
I think most of these are pretty bad, the games pacing doesn't well suit sniping, as people duck and dive between buildings it can be difficult to keep track of a target and placing yourself into any good sniping position. There all as good as you are accurate but for me I found the double take to be the most forgiving and therefore the most effective when accommodating for the highly fast moving battlefield.
I did manage to get some nice collaterals and quick-scopes with the Kraber though, since its one-shot kill potential is quite nice, but still I found it hard to hit targets moving at long distance at times. Are these weapons hitscans or do I need to place some lead on the target? Either way, I don't think snipers are an effective option in any game modes aside pilot TDM and Skirmish so it renders them quite limited compared to others.
Batteries are pointless for Ronin.
Which means I get to use another boost instead.
How are they pointless? I see Ronin as the titan that always has to trade at least a portion of his life to get a kill, so batteries seem quite useful for him.
Titan balance alone is turning me off of this game, attrition devolves into degenerate Legion spam as soon as the first titans come down, can't really queue variety either due to the chance of a 20 min LTS shitfest coming up and PvP is dead on PC
I don't really see legion as being all that great. What gives you issue with him? You can shoot around and through his shield so it's not a huge issue and the fact that he a delay when starting his weapon means gives him very low damage output when being poked at from corners. Nothstar can really wreck him, Tone can hold her own, and even Scorch can deal with him reasonably well if you've got the right environment. I find it difficult with Ion, but it's very doable with good use of your reflection.
At least on console, there's a good variety of Titan's being used. The only one you don't see often is Northstar. While I use her from time to time it really depends on the map and situation as on some she feels quite useless and there's too much risk of getting ambushed in the narrow corridors.
