I honestly never mix armor sets with anyone mid game. It just seems wrong. I even leave on old armor so everyone looks nice till I can find a better armor set. Like I'll leave Shulk with Stellar all the way until after MC and then I'll go hunt for Rafaga pieces. I just don't like mixing armor really. Like the only time it's impossible not to have mixed sets is early game cuz you just won't have good equipment. Also I played like 5 hours today... You suddenly got me playing again >_>
