On one hand having it effect everything makes it pretty much the best buff in the game, on the other hand rdm is already in need of a buff compared to smn. The only "issue" is it could create some really dumb synergy with blm, burning 2 or maybe 3 polyglot stacks during embolden for massive multiplicative buff stacking on the 2 min lineup, but i dont necessarily think party comps that arn't double melee are a problem so just my take
