How are ferals on warmane?
Any bugs or smthing like that?
Are they goood here?

From what I've been reading around the forums rogue are in a very good position PvP wise while ferals I believe are rather weak.
Been seeing a lot of posts saying how a rogue's burst is capable of destroying all of someones HP in a stun.

Although I haven't reached max yet so haven't been able to witness that for myself.
