Lately it has become an huge annoyance to me but this thread is about dps who heals mid fights because they get low and panic.
I get it, you're trying to help but when you have a fully heroic equipped healer who is already bored stupid...you think we need the help?
I already do the interrupts you seem to forget to do because you're too busy doing crappy healing that makes no difference. If you die, then you can complain but for the love of "god" please stop healing yourself and do what you queued to do.
Tip: If you want to help, before starting the dungeon, check the healer. If they are decently geared and seem to have it under control...don't panic to heal and WASTE your dps and make things slower. /endrant
