@Arg: You'd be able to see the overhealing in that case and the cross healing by looking at who was overhealed the most by the Druid on those melee overlapping with the high healing done to those targets by the Shaman. This is again what I was getting at, the meters themselves are a good defense against people using meters poorly to show one person as better, or worse. Rather than ignoring the meters and considering them useless it's better to properly evaluate and defend a position so that tools designed to help evaluate raid performance are used efficiently. There are a lot of people who are blatantly saying lately that healing meters do not matter and mean nothing, rather than actually analyzing a situation and using those numbers to help assess possible problems and causes for them.
