Don't know if its a bug or not but the changes to MBs lightning armor is supposed to remove all debuffs but it doesn't seem to remove anything. Additionally before with the immunity to debuffs you could at least get an opponent to waste an interrupt or acupuncture, or at least avoid a bunch of extra damage that round, but now it really not useful for removing debuffs at all as most people run some kind of control effect in their combo or mystery lineup so you aren't able to activate the ability anyway.
