Why? The only thing fun about Convalescence right now is knowing you can survive something without additional eHP so long as you get healed to the next hit's worth of HP in one fewer healer GCDs, timing it to Regen or in preparation for a (Deployment Tactics) Adloquiem, and so forth. Turning it into a raid-wide just makes that feel... less.

And it's far from necessary or even at all deserved.
