The hitbox issues seem to have been more or less fixed, though not completely.
The current speedy 21 helps to get a few more damage in the corner and makes some combos easier to end, and as some pointed out, f24 now can be easily followed up (offline, online is still hard) by a 12 instead of the d1. This change of speed doesn't seem to have more uses.
F34 is safe, but it should have been this way since the beggining, because is a 2 hit non special cancelable combo...come on xD
Apart from that, stunt double remains more or less the same, A-List (if they correct the rc mistakes) the same, and Fisticuffs is still mediocre.
Anyway, I'm still maining Fisticuffs, hope in the future he gets the help he needs. Seeing that nrs did Kano damage buff comboable, would be great that Cage Fistbump had a similar treatment in next updates.
