Originally Miis were limited to 1111 only, but through my and a few other efforts, they were changed to 1111, 2222, and 3333. It was a compromise we had to make. My original intent was to get them legal 100%. Brawler gets a significant upgrade with 2222 so honestly they're not being nerfed too much from their primary loadout (which I think is 2122 btw). He only loses Onslaught.
Ultimate Uppercut is better than shotput anyways, it has super armor and kills at 80%, forces your opponents to approach you and usually can be charged up for free after a f-throw (your primary throw option when your opponent is past 80% and can't be combo'd with d-throw anymore). Honestly the whole "Cherry picking" would simply be switching Burning Drop Kick to Onslaught and that's it, hardly any difference to begin with.
Apex is allowing mii fighters to use 1111, 2222, and 3333 and I personally think thats a HUGE improvement considering they weren't willing to listen to anything else. They didn't consider it at all until I suggested such a limitation, which again, is hardly a limitation at all.
Anyways, getting off topic here but yeah no since Mii fighters will be at APEX now people better start studying up on them otherwise they're gonna have a bad time.
