One extra button is better than nothing. The low short to standing fierce is especially valuable… if you can do that consistently, you are golden. A combo into ultra off a short is pretty badass. Ultra off a low attack, especially, is awesome to have… say you have done f+mk, standing close roundhouse a few times to land the overhead. Now he is blocking high after f+mk… then you bust out low short, standing fierce, cod, ultra. Not many characters can do that.
Abel’s only real hit confirm combo I’d say is low short, low jab, standing strong xx change of direction… only works against crouching opponents and I’m betting it is character specific, otherwise you get low short, low jab, standing far strong… still combos.
taking one startup frame off crouching mk or mp might work for this, gives better counter-poke options. If anything, c.mk would get that buff… if c.mp was 6 frame startup, you could hit confirm into ultra. c.lk, c.lp, c.lp, c.mp xx change of direction FADC c.fp. That would be fucking awesome but I just don’t see Abel ever having that option.
IMO you don’t even need to be great at that combo. F+MK is never a guaranteed combo but it is a nasty frame trap… you get so many counter hits off it, its not even funny. on CH the 1 frame link becomes a 4 frame link, no big deal at all anymore… that is easy shit, just as easy as Honda’s fierce hands, standing roundhouse.
