Well, for one you're assuming thatvthe K.Rool mii and the ballots are related, which they might be, or might not.
If not, I'd chalk it down to lack of originality. It's been said time and again that K.Rool does little to stand out from Dedede in terms of playstyle. K.Rool supporters always ignored this fact, but it's possible Sakurai didn't.
Really, look at the top 10 and analyze which ones would bring anything new to the table.
That's cool bro. I honestly don't care, but I will tell you it doesn't change the facts. Source and data has been posted, you only need to look at it yourself and form your own conclusions.
