[AskaRay]

SCH

Enmity boosts are exchanged for direct damage.

Eg Butchers block is 280 pot with 5.5x enmity modifier.
New butchers 280x5.5= 1540 potency, but no more enmity boost. Fun fact. Overpower also has a 5x enmity mod >

Bards songs have a duration and straight mana cost when cast and do not debuff the singer's damage. Multiple songs can be active at one time by using the old Everquest technique of "twisting" your songs.

This. This I could get behind, and there'd probably finally be a DPS I can bring myself to play (This is coming from a person who very rarely plays tanks/healers but does so this time b/c I'm having more fun in those roles...)

"Cleric Stance now cannot be used in battles"

OH WAIT, you want to BREAK a class, not FIX IT. Sorry... my bad.
