I guess its good Mii's can't be used online. Or maybe thats why...
When customs are off, equipment is disabled. There is no reason to not allow Mii Fighters in FG outside of lack of time/laziness. Now here my kind friend here called "Devil's Advocate" will list complaints.
1 But Hitler vs Jesus!
Then just allow preset Miis. The Guest Miis, and the placeholder Miis.
Or allow all of them, and allow you to report Miis and quit the match then and there. If your report is random, you get a punishment and can't report Mii users like that. If it doesn't warrant a ban but had good reasoning, you're notified, and so are they. If they'r using Hitler or Satan or something, they get hit with the banhammer, and lose their right to make their own Miis either permanently or for a long time (week).
2. Butbutbut custom moves! How do they work?
Allow them like they normally are with, and have the moves they're using be obvious in some form.
2.5 But that's not fair!
Neither is the lack of platforms for heavies since is polarizes in zoner and Mac's favor. Neither is Omega Lylat, which is an auto win for Jiggly (and Kirby and MK. to lesser extents).
3. What if they end up busted?
This is only an argument with Brawler, and we haven't banned Diddy, so no unfair treatment
4 But I haven't gotten used to them!
Your problem, not mine. Mii mains shouldn't get unfair treatment of not being able to practice if they don't have a nearby scene, simply because people don't wannna adapt.
Who else thinks Mii Fighters deserve to be in FG?
Now back on topic. Using that Java hacking stuff, I have crit perfect shield helper and explosion +200 all equipment at the ready. Now to buy a new charger for my dead 3DS... Where can I get DSi chargers?
