Crits have been changed around and fixed. Rangers will now get a base chance to crit with bows, Rogues with throwing weapons and Warriors with melee weapons. Paladins will be able to crit (cleansing blows) on undead, as the only class who can crit on undead. Other classes than Warriors will need Combat Fury to crit in melee, and other classes than Rogue/Ranger will need Deadeye to crit at range.
I'm no Ranger, but I'm going to have to go with a possible bug.
Two reasons:
1) "Rangers will now get a base chance to crit with bows..."
This specifically says Rangers can now crit with bows.
2) "...and other classes than Rogue/Ranger will need Deadeye to crit at range."
This says that Rogues and Rangers are the only two classes that get to crit at range before AA.
There's my opinion, find my faults =P
