I don't understand why people think Warlock is OP. Personally I think there are on OP classes. Every has it's pros and cons to ballance out any kind of unfair advantage. For example Warlock glide leaves you vulnerable for easy hit, and Voidwalker subclass has been described by Bungie as 'Glass cannon', being strong in ways of offense but takes away from defense. Hunter double and tripple jumps, now that's some useful shit and combined with his mobility and one-shot-kill from golden gun, seriously if there is any class OP it's hunter :P But come on guys/gals, it's Bungie we're talking about. I'm pretty confident they've been testing all 3 for years now to find the perfect ballance and probably they're still under constant development so tweaks here and there will surely be applied if in fact some game-breaking advantage one class has over another.
