There are tanks that never pop any mitigation and DPS that freestyle their rotation so poorly that I, as a Healer, will outDPS them. So why are Healers the exception to the rule? Any half decent Tank can literally carry a group of people thru pretty much every 4 man content with nary an issue, I know because I've carried many a group as a PLD when the healer died and I would never in a thousand years say that I am a great tank. WAR can literally solo an 8 man boss and GNB isn't exactly a slouch in being able to keep teammates up in a pinch so this type of argument is a crock. Bad players exist in every role. That isn't an excuse for keeping the skill ceiling for an entire role as low as humanly possible, especially since the role in the past was much harder to do.
