I have to say the gateway bug is MOST frustrating in arena. There's nothing more awesome than getting trained and spam clicking the gateway for a brief reprieve only to be met with "this spell is not ready yet" or "you cannot perform that action right now" even when the portal clearly has 5 charges...
All in all, I greatly look forward to having my ass handed to me by the fotm rogue and monk rerolls. All I can say is gg smokebomb + ring of peace.
