As a healer I ALWAYS put life before heals, and if the tank is dying and the other healer sleeping then I use Swiftcast or Benediction in the worst case.
If people avoided aoes always nobody would lose to Titan.
And please, tell me your DF secret to get good people, everytime I queue on DF I get people full lv50-45 or full DL that don't know how to dps/keep aggro/heal.
But for now I'm in the Coil as WHM with my relic, so this is not gonna be a problem at the moment.
