Again, nothing wrong with getting broken units in FE4 XD
I guess you could stick Lex with Briggid. Elite on Patty and Faval might help their lower leveled-ness. If not Briggid... Then, yeah, no one .__. I just think Elite's too good to waste.
I was impressed with AyraXLex, but, eh, maybe it was just personal experience. I'm never disappointed with a unit almost promoting after two chapters.
