Can we talk about Miis? The way I see it we have a few options
A) 1111, 2222 and 3333 only, guest miis (default height/weight) only
the difference between palutena and mii customs than all other charcaters is that their customs are completely different moves rather than variation of the same move. Imo, if Palutena is reduced to 1111, so should Miis, likewise if Palutena has full custom move options so should miis
B) Any moveset, guest miis only
Guest Miis are terrible apparently, in terms of stats
C) Any moveset, height and weight must fit into one of 3 categories (tall, middle, short, heavy, middle, light)
as far as i can tell being short is much preferred since it increases speed and reduces lag, then either having light for optimum movement speed and agility or heavy for increased damage and knockback.
D) Any moveset, any height and weight (complete freedom)
This is what Sydney is doing at the moment and will likely stay this way for at least few months until we get more evidence that says we should start restricting the options. In this case I would move to C) then B).
E) Be Attila and ban everything we're scared of
unnecessary
Obviously there are a few other options (any height/weight 1111/2222/3333 only [which would improve the character drastically but is kinda... odd], recommended movesets only) but these are the only ones worth exploring in my opinion.
As far as protocol: players should be required to tell their opponent the weight/height and specials they are using before each match (Sorry Luke, I'll do it if you ask).
Well NSW rules state that the name of any custom build, (MiiS included) be labeled by their custom build number, i also agree that height and weight be given too but it can be gauged pretty easily by looking at the Miis CSP
