I think the Unfezant line has pretty decent designs, so it's a shame they're considered the worst regional birds because of the disconnect between moveset and BST. They had a respectable base Attk stat back in Gen 5, and then come Gen 6 I just found out it was bumped to a really good base 115 Attk. If they had the proper moveset in the first place, I doubt they would've gotten as much hate as they did and still do.
