WAR is only a "healer" in dungeons, their short cooldown actually isn't great in high end content I'd take HoC over Bloodwhetting anyday in exteme/savage/ultimate.

Fact is healers really aren't needed in dungeons anyway and even if they were you would still get healers who don't dps or heal and just throw out a cure I occasionally and afk. The problem isn't with WAR being a "healer" its with most healers being so brain-dead in Duty Finder that other roles needed survivability in casual content.
