Random thought of the day:

Wouldn't it be funny if someone wrote a (redacted heretical mod word) that randomized heals? It'd be a pain in cutting edge content with the need for mitigation sure, and it would introduce some chaos into coordinated groups as you couldn't map specific timers to line up, but I'm thinking dungeons or random party finder groups would barely be affected at all.

Consolidate all of your heals into two buttons: random single-target heal and random AOE heal. Press one, and it'll select one of your currently-available heals in that category, GCD or otherwise. See how big the difference is in your Expert roulette experience. See if it makes clearing an EX trial an impossible, harrowing experience.

My hypothesis: apart from randomly GCD healing when you least expect it, if you're remotely skilled as a healer, you'll barely notice. This is what I think of when people act like these healing kits are remotely interesting or in any way a significant step up from the boring damage portion of the kits.
