Wow, quick to the personal attacks. Internets sure is serious business.
It's not only my idea, it was mentioned earlier in the thread as well by someone else, and I'm sure others have come to this conclusion on their own as well. I merely provided an illustration of my theory.
I don't see the purpose of a character portrait on it's own, but as a placeholder for when a user isn't playing their Mii profile to track their wins, losses, etcetera, then it makes sense.
I wouldn't immediately put down and throw aside your theories on anything, and I don't even know you. So let's chill a little and explain why exactly you think it's a stupid idea.
Do you dislike the portraits in general? Would tracking stats linked to a Mii online be a bad idea? It's being used in Mario Strikers in a similar fashion.
Constructive comments, those are the good ones. Do you have those?
