I thought Yoshi wants healer to focus on healing only..

then i think the game design have some fundamental issue
shouldn't a healer there to make room for player making mistake, not a lot and not the serious one of cause
but if Healer is only needed in those raid wide damage, arent it a bit boring, just like playing a rhythm game, you memorize the whole fight, and push the right button at the right time, zero dynamic

All fights in FFXIV are scripted.
All bosses will throw out mechanics in the exact same order, with the only exception being enrage timers triggering early due to slow add kills
