Hunters need +crit (after they reach +9% hit).
Not sure about pre-1.4 gear, but in full MC gear they should go for about 20%/22% crit.
With raid buffs (and possibly a feral druud), they're going for around 35%/40% crit.
Even on feenix, with the retard melee buff-stacking shite, hunters perform well, at least till BWL (I only know about ED). Sure, they cannot compete with warriors...but was it blizzlike 2000ap and more than 50% crit during t2? Don't think so.
Clearly, with AQ, mage&ignites gonna be quite hard to beat, but I strongly believe hunters could put up a good fight even there (Earthstriker? Jom Gabbar?? anyone?)
Really, 90% of people posting here, imho, are tainted by feenix and dps chart there....
...they won't even consider how broken melee dps is, there.
So, all in all, say that hunters are shit dps, just cause the cannot top meter in Naxx, is bullshit. They most likely top meter in all lower tiers.
