The fuck is a Hunter?
Come end game the two most OP characters WHEN GEARED are Cleric and Templar.
Both require extreme skill and how to use the class properly, such as switching weapons WHILST weaving as a templar.
But both are designed to have extreme survivability.
Don't roll assassin, they're fun, appealing, but too much work/expensive to be any good. They're a real kinah sink, and most people that roll them and get geared usually quit, just because of how effortless everyone else had it to do the same things they did.
I love my sin, but I don't wanna fall into that same group.
for general PvP though I'd recommend:
Glad
Sorc
Spiritmaster
Ranger
Cleric
Assassins are too much work for what they can do, and require absolute perfect ping to perfom (Which is why Korean Sins do so well)
Chanters are fun, challenging, but have it worse than sins -- although people will always want you for groups (if you plan on Group pvping(Small scale), this is one of the better ones to roll as

)
Templars aren't good until you know the class/gg geared/end game. Haven't raised my templar so I can't say much, but I've heard it's hell til that point.
Really though, choose something you think you'll have the most fun with. After finally hitting level cap with my glad, I realized there are several other classes that are more fun.
Then again, it's always nice to smash kids 1v2-4 as a glad
