options, it would be rules on options because said options are pain in the butt to regulate and discuss at a meta-level.
Someone else might want to pick a character and you are entertaining the idea of banning them because it
might be a problem in the future to regulate or discuss?
You shouldn't be suggesting this kind of stuff at all when you have literally no information on the subject whatsoever to provide. You're blowing hot air right now about something that
could be an issue down the road but
we have no idea. It's not very constructive and potentially dangerous.
What is with everyone being rule happy? Prior to the game's release people have already decided to champion banning equipment, custom moves, Mii Fighters save for the shortest, tallest, and middle height and weights, Mii Fighters entirely, all Miis but the default, Palutena specials, G&W and pikachu team, double villager teams, every stage but FD, all FDs, all stages but three to five, doubles itself, and games over two stock.
These kinds of suggestions like "oh man, Mii Fighters could be an issue" are very easy to think up and they're good to be aware of... but the next step isn't discussing "should we ban Mii Fighters" but rather "What data do we need to have to determine if Miis are going to be an issue" and then collecting that information.
Yes, Miis might be a pain. But saying "ugh, my opponent wants to create a Mii" should lead to
banning them entirely is a pretty selfish action. Someone might want to play as that character and until we have data to go off of we shouldn't be making plans or conclusions of any sort.
Imagine if Miis actually ARE an annoyance at tournaments. Say it takes 2 minutes for someone to make their Mii on the Wii U version. In what scenario does this constitute banning them?
If Miis aren't popular after the dust settles, then it's a non-issue. You'd have maybe one or two guys using 'em.
If Mii's are popular, banning them is counter productive because people want to play as them.
The only time it is actually a concrete issue is when you're in some hazy middle ground.
