Hunters are ok in pve, not so much in pvp. Focus is awesome, much better than mana. But the method you regen it (Steady / Cobra shots) is a fucking terrible for pvp(aspect of the fox is also terrible, they told us they didnt want us aspect dancing). Hunters will probably be fixed mid to late s9, after they have a horrid representation in RBGs and Arena's.
If you dont wanna do end game pvp, Hunter is great.
