Personally I think Yoshi's team has been hugely uninventive with healing as a whole, cleric stance is just the most immediately obvious example to anyone.

Imo a more significant case where SE have dug themselves into a corner would be the 2hour or boss transition phases they've kept going back to repeatedly. Everytime it ends up with apply bubbles, maybe sprinkle some mitigation ontop of that and afk for a moment. It allows for some flashy effects, but it doesn't help the gameplay along. It'd be a lot more interesting to have this big transitions come as multiple hits more in line with T13's flatten+flare breaths or the phase 1 preys in A12s. You can bubble through them or you can heal them with well timed brute force, either way is far more engaging than a single big hit and it opens up more many more options for groups to get past it.

Here's hoping SE have learnt their lesson and spent a little more time and effort on the healing side of things this expansion.
