Has anyone quit healing?

Healer DPS kind of "has to be" taken into consideration for enrage. No fight, not even P8S, demands 100% healing GCD uptime. In fact, I took a look at the lowest scoring recorded clear for P8S II of the last couple weeks which contained a WHM and a SGE. Raise and Egeiro were cast twice by each healer (not sure if these were on 4 separate deaths or if they raised the same targets) which is to say it wasn't the cleanest clear.

The WHM spent approximately 72% of their GCD on DPS tools whereas the SGE spent approximately 90% of their GCD on DPS tools (I included Pneuma as DPS as it's a DPS neutral button and we're discussing damage dealt to bosses from healers). They were responsible for approximately 19% of the boss' HP. Now, we're far beyond initial clears of this raid tier, so these are obviously not representative of launch week numbers, but even if we were to halve these values, that's still a fairly significant amount of damage coming from healers. If that wasn't factored in, parties could cut a fight a couple minutes short. And again, this is P8S II, a fight with very demanding healing requirements respective to the rest of the game. What choice do the developers have if they don't want parties to end fights several minutes early?
