I don't believe the tick system would allow them to do 2.0 intervals. And it may not be overpowered but it's certainly unbalanced. That special attack means that mages who are already disadvantaged towards ranged attacks are going to punished even further. Not to mention that this would drastically affect hybrid although I'm not sure if it'd be good (promoting ranged in the hybrid scene) or bad (spec would be high risk low reward since the opponent could switch on their melee armor) All in all I really don't think it's a necessary change, current seercull spec has its uses (niche, as any special attack should be). With decent timing you could completely take someone off guard
