She's my favorite FE4 character so ofc I pulled for her.
This whole debacle was pretty scummy but ¯\_(ツ)_/¯ I use her regularly because she's pretty fun to use and doesn't drag down my arena score. I don't even care about swift sparrow, I replaced it with fury for the extra bulk and EP offense.
Powercreep? BST wise, sure, maybe, but fighting her in arena isn't a problem. Using her on offense is pretty ridiculous, but without player control she's really not that much of a threat.
