I have life giver with Empower, but not the regen one. For a while there fully charging would properly fill mana of all allies within range along with the heal. Recently it fills mana for those who are not sorcerers but when I'm standing on top of another sorcerer and release a fully charged lifegiver it seems to skip over them as often as not (hard to know if someone is hitting a mana pot - it might be always)

At the last free respec, through a lot of testing, I decided on just empower because that is what allowed me to refill health and mana without pulling aggro so I became pretty observant of how it hits. It was all working well then. Since then, you've had an update to lifegiver aggro and that is when this seems to work a little differently. Shouldn't lifegiver empower hit all allies equally regardless of class?
