Personally I think she's fine. j.S > j.D corner loops are easy to confirm and decent meterless damage. Air Tatami is a bit slower but still a solid oki tool. Her pressure and mixup game isn't stellar but a good Baiken player will make sure the opponent is scared of an Azami and CH follow-up.
That will be the key to making Baiken a real threat, smart use of Azami.
As for Answer, I dunno. From the footage i've seen he likes to go nuts with IAD mixups and jumping everywhere on his kites. I think people will have a huge problem with him at first until they learn to deal with his kites. Then he'll settle.
