What you think Birdie needs? Because I honestly don't think he needs to be changed much.
Medium chain grab should go full screen. It's currently a useless move.
I'd like the startup of the chain stance improved too. I'm fine with the chain throw itself being slowed down to compensate. As it stands he has a chain stance cancel which is totally useless.
It sounds like normal BR has been sped up a bit, which was needed as they were, again, nearly-useless moves.
Bull horn changed to dragon punch motion. Having a character who relies on using all his buttons have to hold down buttons to actually use a special move is idiotic.
Donut startup sped up by a few frames to make it a worthwhile version of his v-skill. It's a fake-out and should work as such.
Anything else is gravy, but I want his currently bad moves improved to be non-gimmick parts of his strategy. As it stands Birdie and Gief are the two characters that stick out to me as the most unfinished and unbalanced of the main cast (with Juri filling that role for the DLC) so I expected them to get the MOST changes, not, in Birdie's case, the least.
Basically, I want what was promised with Birdie - a semi-grappler with lots of options but slow walk speed, instead of a character that relies 100% on flipping a honest/dishonest switch half way through the match.
