Yeah. they definitely leave out telling you about timing delays and how to get assist going. I'm figuring it out, but I can see a casual person never getting these down.
You really gotta play with timings in this game. For skrull and taskmaster i often go LM, slight delay H, slight delay again, then whatever just to do a hit confirm. Where as x-23 i just mash L till I see a confirm and then go barreling through the sequence. With taskmaster to do his corner OTG set up w/ assist:
blah blah, S, j.MMHS, Assist, j.236H
you do it like this:
blah blah S., jump, pause, M at height of it, pause, MHS as you fall, assist + jump, 236H
If you just do MMHS they fall way to early and you dont have time to get the OTG or the assist.
Also that lil theory i had on a layout...lol no. it doesnt work well. Best to go with the TvC-esque type B. Layout wise I think this is a rare moment a 4 button controller with shoulders may best an arcade stick...you just give up the accuracy of a stick for direction.
