I dunno…I don’t think eryu has any mandatory 1f links, except maybe tatsu, sweep on the characters it works on. After a dive kick, just go straight to cl.mp xx mk axe kick. It’s a true block string, and due to scaling silliness, doesn’t do any less damage than the 1f link you’re complaining about.
Eryu can also do 2 light attacks into cl.hp in a ton of situations. Meaty c.lk into c.lp, cl.hp works on a ton of characters. Meaty dive kick you can do 2 lights into it, too, but it does less damage than just doing cl.mp xx mk axe kick.
I’ve been using lk axe kick, fadc, c.mp a lot lately, which is hard and leads to combos with a ton of 1f links, but I wouldn’t call that mandatory.
Also…f.mp, hp srk isn’t useless. You have time to hit confirm and it does sometimes hit people when they’re standing. They could have tried to walk forward or focus or w/e. I’ve hit it in matches before. Usually when my overhead hits focus.
