BBTag patch 1.50 is out, investigating some basic things for my team (Yukiko and Tager).
Not much has changed for Yukiko and Tager actually, mostly the changes to Yukiko's Maragi and Maragion both give some new combo potential and a bit more damage than in previous patches, but they're basically the same as before.
Not complaining though, Yukiko needs all the help she can get and Tager probably doesn't need anything considering how dangerous he is when paired with better characters.
