Not to throw a wrong ball here, but you could also consider Sumazinti Velcoffer Set.
It’s not as good for improving your recovery value, but it adds the unique ability to decrease the enemies defense by 25% for 10 seconds or 30% for 15 seconds at Dragon Strengh 1 with a +3 Cleric Boruta Seal(skill has the usual 100 seconds cool down time).
This is actually pretty helpful, considering the fact that IMC is slowly decreasing the defense ignore effects on skills and attributes as well as the defense reduction from skills and attributes.
However,you don’t have to consider this at all if all you want is to improve your healing to a point where you can simply outheal the HP pool of most people in the game, I just put that here as an option that would provide useful support aside of recovery.
