Why couldn't Marth bair w/o needing to turn around
He'd be SO much better
Completely opposite arc from fair, stops AAs that stop fair (as a result of fair's arc that is)

Marth's fair being one of the few moves in the game with misleading frame data.
SO SLOW IN FRONT~

ughhh
I knowww
I hate when people go "lol, you can't PS it, it's frame 4!"
No, doesn't work that way.
Basically, despite what the frame data says, Marth's fair is a much bigger commitment than it seems. He has to commit to the approach, move forward in the air, input the aerial, and wait for fair to come through the arc. ZSS's ftilt just sticks her leg out there and stuffs the approach really hard.
