it might be like oh so many other classes.....
i rarely see warriors hit me hard on Naklin.
also not hunters, and also not rogues.
actually anything that isn't casting is hitting me hard. even on cloth.
but they hit often, and when they use their special abilities, it hurts like hell.
with my blue level 60 hunter i do about 200-300 dmg per shot with a good bow and having about 1000 AP unbuffed now.
its when i include aimed shot in rotation, that i get to 2000-3000 dmg crits.
Rogues are the same... they do squat until their energy is high enough or they have enough combo points. besides thoses moments, they do tiny yizibitsy damage.
casters (like mages) do high damage (if geared well) on every cast almost, but they cast only once every 2-3 seconds, depending on spell..... and lose mana.... thats where blizzard tried to balance it out.
i think with your crit THAT high at not even level 60, its VERY VERY decent.
and in PVP it should hurt... a LOT..... if you PVP, you will want to go for high crits and forget about sustained damage.
my 2 cents
Come and join on Starcraft 2 as well =]
