That's where they shine though. Skating and using Shoulder Charge makes them the fastest and most maneuverable class when played at a high level.
What limits their PvP appeal is the lack of a ranged super, a grenade with tracking or proximity damage like Arc/Fire bolt, and a terribly useless melee. I don't think it's strictly about the movement itself, but rather the lack of compelling abilities on the skill tree.
Bladedancers have: QuickDraw (best PvP perk), a one-hit melee (technically from the back only but it's easy to one shot with a side stab), and a melee where they retain control over their grenade, move super quickly, gain 2x health. They can also go invisible and use their super at a (short but useful) range with Razor's Edge.
Gunslingers have arguably the best PvP super: long range, precision, and will multi kill grouped targets. They have a long distance melee. Interesting grenades, buffs to weapon stability, aerial domination with their tight precise jumps...
Sunsingers are beast. Superburn grenades with proximity tag, Viking Funeral for ridiculous health buff, melee with instant shield and long range, crazy OP super.
Voidwalkers have blink, a long melee which feeds them health, tracking grenades, a ranged super...
Titans' PvP handicap is not a "oh add Blink and there's parity" deal. The entire perk tree is lackluster for PvP compared to the other classes. No Buff on melee hit, no tagging grenades, no skill tree buffs to ADS speed or stability or DoT damage, nothing.
Some great players like Unstable or AEGabriel can wreck with a Titan, but these guys would wreck with anything. Player skill aside, the Titan ability tree just doesn't do anything to help your PvP game.
Here is a great post on the Destiny sub-reddit regarding class balance when it comes to Titans from Pwadigy:
"I'm sorry, this thread is downright wrong.
any PvP player can tell you that anything outside of Sunsinger and bladedancer aren't competitive. Yes, there is one good player who runs striker and does well in tournaments, AEgabriel. And there are very, very, very, very few void-walkers and gunslingers. Defender Titan has not done well in any competitive tournament.
I'm talking players who are so good, that they only play good players in sweaties. All of them are blade-dancer and sunsinger. Except one striker Titan (He uses Titan skating and shoulder-charge for mobility, others have tried this, but the learning curve is so high compared to reward that it doesn't work out).
Bolt grenades are objectively more competitive than other grenades. They are more versatile.
Flame-shield is the best melee, hands down. Mechanic for mechanic.
this kind of thread is bad for the PvP community
It's blatant misinformation.
Any time you have variation that is not horizontal, you will have something that is better than another. If the composite parts do not offer enough horizontal alternatives, but are instead merely vertical lessers, then the entire whole is lesser.
Likewise, tit-for-tat, the classes are not equal.
High-level PvP (best against best) stabilizes on versatility. If a grenade can do more consistently with less interfering input from another player, it is a better grenade.
Most players aren't familiar with this kind of play, as this game has no custom lobbies. But I'm talking about the kind of play where even trip-mines and Lightning grenades end up being too inflexible.
In case you were wondering, the competitive showing in tournaments looks approximately something like this:
45% Bladedancer
45% Sunsinger (note: ram is generally forbidden in competitive matches)
4% Voidwalker
2% Gunslinger
4% Striker
Pub-stomping is entirely different (6v6 lists). But when you distill the game down to the best, you have only a couple classes that maintain flexibility.
This is what we call a meta, and there is room in our meta for a decent Titan class. Bungie just has to give it a few more competitive options
Please, don't be another player suggesting that everything is equal with vague arguments like "each has their own strengths and weaknesses." This is merely pandering to an ideal that we think should be true. In reality, we can objectively compare the classes. We have a subreddit for this called /r/crucibleplaybook[2] . And we generally look at this stuff in more detail.
The general consensus on classes is as follows:
Blade-dancer: Competitive grenade. High mobility. Decent Melee. Best Possible side-perks (QD). Solid Super
Gunslinger: No competitive grenade. Decent Mobility. Decent Melee. Underwhelming side-perks. Best Super
Void-walker: decently competitve grenade. Decent Mobility. Strong Melee. Decent Side-perks. Decent Super
Sunsinger: Best Grenade. Low mobility. Best Melee. Solid side-perks. Decent Super.
Striker: No Competitive grenade. Highest Mobility. Bad melee. Bad side-perks. Decent Super
Defender: No competitive grenade. High speed, low mobility. Bad melee. Bad side-perks. Bad super.
Side-note: Supressor grenades are bad. they are easy to blink and move out of. Also, effectiveness with and against a super is the last thing you look at when analyzing a sub-class.
EDIT: soz @ OP for tanking this thread, I had Ram and flame-shield."
