this is what aerez is designed for, for N clerics to rez w/o overlap while other clerics keep healing. thats pretty much the best its going to get for a long time, too complicated to manage all the heal vs rez vs other clerics logic otherwise
On a related note, would the easiest way to rez up after a wipe be: /bc summon corpses ;Wait for all characters to get their plat, buy the soulstone, and summon their corpse /aerez
