It's been said MANY TIMES NOW by Yoshi P himself that no content is designed with healer dps in mind.
A few answers to this:

If you're one of the healers who doesnt dps, and just heals, and a significant amount of healers actually do damage and keep parties alive while doing it, you are, in comparison to the whole, a bad player. If you spend multiple cooldowns to do what you can do with 1, you are, relative to the whole, a bad player. And if you KNOW you can do it with less, and free up more time to optimize your output, but choose not to, you're square in the "willfully ignorant" pile.


Additionally, if you've played MMO's (or games in general), you'd learn not to take things people say about their content as gospel.

I've been assured, by Sony, Blizzard, Squenix, Nintendo, and others, that "x is working correctly" or "x content is not bugged" or "x is intended" only to see those be hotfixed, patched, removed, re-broken, swapped out or re-implemented.
