Thing is nowadays tanks are so OP that they barely need heals in dungeons lately, hell I have seen bosses over 50% HP being taken down with the healer dead.

Instead if there was more unavoidable damage to actually HEAL in dungeons/raids, then healing jobs could be more engaging, not silly ideas like add another attack to healers kit. If you like to do damage go play a DPS, the healer job is to HEAL, contrary to popular opinion I think our attacking skills are enough.
