No, I don't care that Dixie is in. That does not make up for no K. Rool. It means that half of you can be content with Dixie alone, and the non DK fans can just make cries of "relevancy" and be happy about it because they like literally anything that is served to them. Dixie will be accepted by DK fans and K. Rool will be dead and buried. He needed this. Far more so than Ridley and Mewtwo, he badly, badly needed this. He was the true protagonist going into SSB4, with Ridley and Mewtwo as his sidekicks. Alas, he was killed in the end by his eternal rival, Dixie Kong, whom you lot told me several times wasn't worth attacking.
If you don't believe the cancerous fans of this series will accept anything, keep in mind we have Dark Pit apologists now, and Duck Hunt Dog's reception is almost entirely positive.
When looking at each and every single newcomer, keep in mind they were all chosen over K. Rool, as well as Wolf, Ice Climbers, Lucas, Ivysaur, Squirtle, and Snake.
Mii was chosen 3 times over K. Rool, in fact! He's 3 times more important!
Anybody can be "fun", the people that are in are not more fun than the people that aren't in simply because they're in, contrary to popular belief. If anything, several of them are quite pitifully low potential characters, much less compared to K. Rool. I thought this was a game where iconic Nintendo characters fought one another, not an advertisement crossover game.
Oh, and yeah, Dixie Kong does fall under "advertisement". Tropical Freeze was her first appearance that wasn't a cameo, a remake, or a spin off in 18 years. Tropical Freeze is the only argument one can use to justify her over K. Rool in any fashion, as she was never terribly "relevant" herself. She has fans, but they're only a fraction of K. Rool's, as the size of both their threads can plainly tell you.
