Yup. Not against catalyst diversity. Touched on it on @Dusty00's thread - https://forum.skullgirlsmobile.com/threads/rift-attacker-diversity.15954/#post-39627 . Reason for not going into it here is as stated : In a stall modifier, catalyst diversity is definitely needed. Not sure for dynamic modifiers though. Have to test it firsthand before saying anything conclusive. Surgeon and couple other variants can be abused on most stall and dynamic modifiers.
