As hunters we have a fair amount of CCs but the problem is they are just slows or breakables. Mean while other classes get to stop you and shit all over while you are stuck. and then if not a stun a better heal, freeze traping them and bandaging up isn't the same as iceblock, monk, priest and pally bubbles.
Playing arenas and coliseum already puts us at a disadvantage with the small space and lack of self heals. So as a dps class we need to be able to wreck on a healer class faster than they can heal else stop them (counter shot just isn't as good as silence was)
