If you use Chun as a 2nd slot, then without an OTG assist, your Chun-li will have to fight in a manner very different from the way we use her.
As a DHC, Chun-li works well with Wolverine. Together, they do a lot of damage with DHC’s since their hyper combos are shaped similarly. But if Wolverine dies, I don’t think your Chun-li/Akuma team will work out against zoners and keep away. Also, your direct damage dealing is very bad. Chun-li gains the majority of her meter from air combos, and after that air combo hits you won’t have any way of using that meter to finish off your opponent since Chun-li can’t OTG, ground bounce, or relaunch like Wolverine can. Lastly, with your team, Chun-li can’t convert any air throws into damage. Akuma could, but that’s not the way your team is set up.
But, I still think that there are strategies you could master in order to do competent damage with your team. If your opponent is an annoying runaway type who knows that you can’t do damage off of a throw, then switch to Akuma.
Avoid using hard knockdowns with Chun-li since you can’t otg and use aerial exchanges for your offensive damage. Chun-li’s huge meter gain can be used by Akuma to do great damage. Assuming you’re using Chun’s Legs assist, you could use aerial exchanges to do extended Chun/Akuma exchange combos. After any Chun combo, you should have at the very least 1.5 meter gained. When added to the meter gain from exchanging into Akuma, you should have enough meter to do one of his meter-intensive combos featuring multiple Beam supers.
For example, a Chun-li ground combo xx full Chun-li air combo xx exchange into Akuma xx Hard Knock down xx OTG relaunch xx Fireballs super xx Hard Knockdown xx Chun Legs assist xx OTG xx relaunch xx fireballs super xx hard knockdown xx air beam super. All of that could be done from 0 meters from a single hit confirmed Kikoanken.
Assuming that Chun-li dies, since Chun-li doesn’t use meter in, you’ll be left with an Akuma fully loaded on meter and (hopefully) x factor lvl3. Which is a good position for him to be in.
To sum it up, I think you should chose another character as your 2nd slot because your Chun-li/Akuma team poses minimal danger damage-wise, and you have to resort to risky aerial exchanges to make up for that. I suggest Felicia or Wesker, someone who is able to do damage off of a grab or OTG by themselves. Or just switch your team order and play Chunli/Wolverine/Akuma, which would solve all of your problems instantly.
Actually, yeah. You should just do that. Chunli/Wolverine/Akuma sounds quite good.
