I see a lot of people saying how skills like Kanons are redundant with his BB heal/negate status ailments,  but not many people being thankful for a unit that can maintain his usefulness when a fight like zevalhua trial when leader skills get locked,  and whoops,  there goes nullification and you accidently forgot to equip drevas/refining gem because your ls covered it. I think that is the best reason for some skills redundant nature
