I have already reslotted enhancements on my empath.
My heal aura has gone down to 257 Heal from 435 (i think)
3 heals and 3 recharge
Heal other is now 535 from 800ish
3 heals and 3 recharge
RA is now 3 end rec and 3 recharge
Regen is now 3 heals and 3 recharge
AB is 3 recharge and 3 end rec
seems to be ok i can still solo mishes on heroic (just).
I have left hasten as it is, so that in a tight squeeze i can use it and then heal like i used to before I6.
