I don't think the complaint is about the idea behind them, it's about the functionality. Realistically, you have a grenade and a melee that isn't particularly different. If you boil it down, all three have a kind of nuke super (assuming nova bomb/foh/bladedancer is considered nuke) and all three have a unique. Locks have the lore-specific revive with sunsinger, Titans have the role-specific bubble, and hunters have the class-specific golden gun. But beyond that, there really is no difference. Varying levels of range and speed for Melee with specific perks. Grenades that are largely identical. I think the problem is in FPS PvP it's hard to provide a huge level of differentiation, what differentiation there is is compared to the 3 loadout system you mentioned above. It's like in CoD, you prestige and start at Level 1 with three loadouts, and even though it probably isn't ideal for your playstyle, you can wreck shop. That was the expectation, I think, so in this, when one class has something different, people cry foul. Ultimately though, I think they're as different as can be for now, but hopefully we see some big changes coming soon. I don't think it needs a complete overhaul, but I like change.
