Hunters is, in my opinion, the best class for survivability, whether in PvP or PvE. Of course, you need to actually understand what the hell you are doing with a Hunter... Triple jump offers much better control than the glide - I have an easier time in platforming sections with that than anything else. Golden Gun and Arc Blade are not like the Warlock or Titan supers - they are situational supers that one needs to understand instead of just firing off in the heat of the moment (like the Striker and VW supers). Sunsingers Radiance is nice in PvE teams if you have it spec'd accordingly, or you can have self-res. Your call I guess. The Defenders Bubble is also situational - just like both Hunter supers - if you just fire it off, then it is wasted. Point is, if your playstyle is such that you want to run into a group that will kill you in a heartbeat, but you insist on being Billy Badass's idiot cousin Danny Dumbass, then by all means take the Warlock class. No worries though, bruh - my Hunter will revive you when your super is gone, and you are crying in the corner complaining about how the game is OP. ;-)
