We were nerfed straight across the board. But black arrow now has no CD and does 1,051% weapon damage, plus the new 15% increase in damage from the new ability = 1208.65% weapon damage. Couple that with the additional AoE utilities... I think hunters will be quite viable in all encounters.
But to your single target output... I still see possible nerfs once 5.0 is released.
Single target rotation will be way too simple and boring though.
