They are not the best 1 v 1 class.
They do not have the highest dps or burst.
They do have high mobility but not the best mobility
They can stealth alot, but its easy to counter if you think about before whining.
They can escape a battle at will, but that means they lost.
They have aweful group utility
Most of their weapon sets suck
They are forced into a single spec because the rest suck
i could go on with this, but the reason you are whining about theives is not because of the thief, its because you got caught with your pants down, and in your shock you panic and died.
No one likes to lose, deal with it, if you’d have seen him first you would have killed him, do you think he would be here whining about which ever class that was?
