I played a druid in WoW - when I wasn't on my rogue. And, to be honest, I was good at it. Healers were so far between in WoW that you better not blame yours without a good reason - and most people didn't.
People who blame their healer for what is most likely the entire group's fault - or one single entity in that group's fault, for that matter - are idiots.
Just my $0.02 on this issue.
Back on topic, I can't see myself playing a healer to being with simply because that's not my style.
