its not healers per se its just this games perpetual problem with class/spec stacking. One or two sorc healers on the other team? No problem, but 4 sorc healers on the other team cross healing each other and well, nothing is probably gonna die since they're just gonna heal each other. This isn't really just a healer issue though because fighting a lot of anything is gonna suck, like 4 mercs or 4 snipers on the same team.
