I just thought up an idea, i could see a rdm, and a brd equivolent, and perhaps share it to sch, but im not sure if that would apply, but i have an idea for a fun debuff, could be balanced by duration, recast, or effect.

Parochialism - Forces special moves by target to only activate upon the target with the highest enmity.

Now this could be used for a single tp move, then wear off, or be a set duration (before resists) and have a longer recast so this cant be done all the time, though this wouldnt affect aoe spells. This could also (maybe?) prevent some shadow whiping tp moves not dispel the tank's shadows, and this is a substantially powerful party and endgame (HNM?) related enhancement.
