Or they can do the oposit but will be harder since whm don’t have any type of party shield anymore. (Rip Stoneskin)

In this case, they could rename the current Protect to Wall, add Protect and Shell to WHM. And then give them a form to spread Protect/Shell to everyone or add something similar to Protectra and Shellra that uses a lillie stack. Something like the ACN's Bane, but with buffs.
