I have HotKeyNet configured to use mouseover healing. With my unit frames configured through Pitbull healing is a piece of cake, even going from 5-man to raid. Doesn't matter what healer I use, what toons I'm using, raid, partial group, full group, subbing in alts, as long as the healer is set up with the proper /cast [@mouseover] Healspell, I'm good to go.
