Just because you don't gain the 20% bonus mitigation from being in tank stance doesn't mean that the healer is working 20% harder. Speaking as somebody who's both tanked and healed content at every level in the game, there simply isn't anything in this game outside of Savage that can't be healed with OGCDs, the occasional shield, and regens. I've healed entire EXRs with Paladins that never leave Sword Oath, and Benison, Tetra, Regen, and Asylum carry me the entire way through while I just set up Aero III and holy bomb.

It's a matter of comfort and experience. And, yes, that does include going into your DPS stance once you've completed your hero pull: most of them aren't actually that dangerous as long as you're using your cooldowns properly.
