I mis-wrote what I was trying to say, HPS is obviously important, but it shouldn't be the yardstick to which healers are measured.
Granted proper raiding is different, and it is hard to measure a good healer using meters, but I find myself using Healing Rain on the clump of players, even when not required, just so I don't get kicked out for not performing.
cool. Yeah, most people read healing meters incorrectly (just like most people read "DPS" meters incorrectly). Healing meters are a little tougher to read contextually.
perhaps... but learning how to blast out as much healing & maximize our mana regen are good habits to build for when you find yourself in a real raid where it will be needed.
