Staff AoE abilities would just be so much fun, especially when bringing lots of physicality to it. Your 234 and 5 could all be a different AoE's that has different forms of soft to hard cc. And the burst could be something wild like flinging opponents into the air and letting them take light fall dmg lol. Also adding an extra bar of adrenaline, and making all the regular bursts do more dmg without the perks they currently grant (evis- stacks of might, arcing slice-fury, etc.) would be cool. Then we'd have four stacks of adrenaline and could go wild with our bursts. Not OP at all lol
