You're not from around here, are you?
healing meters on boss fights are really dependent on the type of fight and the healing assignment that you really cant tell anything from the meter. unless u have 2 of x class doing the same thing and one is outhealing the other by a fair amount like on vashj p2.
trash healing meter tho, i think can give you a pretty good indication who is on the ball and who's just afk half the time.
