Bunny Skill: I actually think it's decent. A ranged spammable, heavily influenced by AC, skill. What's not to like.
Buffalo Skill: Pure sexiness. So good! I love it! 8D
Who doesn't like a ranged Berkserk?
Dragon: I'm not too sure, I haven't seen many Pure Dark Dragons, but it could be cool. The new Light skill could be pretty good.
Sheep: So-so. Definitely not for PvP.
Lion: Well, I think it's pretty decent, seeing as Lions hit criticals...
