Was surprised Warlocks are lower than Titans, I actually enjoy my warlock much more than my Titan and feel that overall Titans are the worst suited for PVP, especially since they lack blink. I wouldn't necessarily say hunters are overpowered, but they are the easiest/low maintenance class to master for PVP. Both of their supers are very well suited to PVP and you have exotics that enhance both of them in terms of arc blade duration and giving them an extra golden gun shot. Personally I feel Hunters are the worst class to play in PVE, but they are geared more towards PVP with their abilities. The one drawback is they can be killed when activating their super, where with Warlock/Titan if you hit your super but die before it fires you still get to keep it. With a hunter if you are killed during your activation sequence you lose your super completely. Also people tend to go for hunters because they see all the better PVP players using, again because they are the easiest class to really master for PVP and when you get really good with them you can do some work in the crucible. You have the risk of being killed in your super, but when you get good enough to know when to activate it you can easily get 4-5 kills like its nothing with Arc Blade/Golden Gun. I've always found it much tougher to get big multi-kills on my titan and warlock with their supers. Hunters just make everything a bit easier, especially when you add in things like invisibility, but you still have to know how to use the class to be good with it. Personally I think Warlocks are better, but require a bit more knowledge and ability to play.
