Check the Rankings, EA's already getting most of kills. Guess why? the CT on gear is too easy to get and makes it easy for them to kill LA / HA classes, not to metion they also can change to aps set without any issue, Blood Vow CD was already reduced. I find fair the way blessings work right now.
as for clerics the mana blessing is not really necessary, you could just equip the marriage ring and still PK without any issue
