I know not technically a parse but had to share the new changes I did for my healer.
Could still be higher, working on 1x piece Iceheart instead of chokethorn for 3.1% crit, minor prophecy from sorcs is another 3.1%, replacing my 3 infused with divines will be another 2.4% bringing the grand total potential to 85% spell critical on a healer.
the reason? a non critical vs critical heal with the CP changes is 80%, 90% if you slot an Aedric Spear ability. My old crit with the atronach and mending was 48.4%. Therefore theoretically the new build with 36.6% extra crit is 29.28 - 32.94% more healing overall than my old build.
Put this together with Illustrious Healing since 2x healing springs don't stack but rather refresh duration and you have the el del healing supreme.
Note: There's absolutely nothing wrong with the way anybody already heals, this is just how I'm going to run.
