This is actually a really good point and im glad you made that edit because i hadnt considered it that way.well it seems like you're forgetting that the so-called "neutrals" do still present advantages to certain characters, without needing to add "gay" elements
edit: to better explain, using your scenario
let's say on some imaginary perfectly neutral stage, you are a 7 and your opponent is a 6
now if you go to something like yoshi's story, you are an 8 while your opponent is a 6
however, if you go to something like jungle japes, instead of being a solid number, you are now something like a 7-9, while your opponent is a 5-7 (this is what i mean by variance); you've just introduced the 'chance' that you will be perfectly evenly matched (7-7) based purely on hard/impossible-to-control stage elements
if you feel 8-6 is a solid enough advantage, you take that and roll with it, instead of rolling the dice hoping to get a 9-5 when you could just as easily get a 7-7
note: these "numbers" are meaningless so i hope nobody reads too much into them (i.e. this post is directed specifically at 'JPOBS' since you defined the system and probably know what i mean when using the numbers; nobody else should try to 'interpret' what i'm saying here)
good post.
