Because more than a handful of K. Rool supporters (weirdly enough it's worse here than a lot of other places) act like everything is a threat or have incredibly shortsighted and entitled attitudes when it comes to character additions.
Everything that debuted after 2008 is "an advertisement." Anything that isn't cartoony is "irrelevant weeb trash." K. Rool "obviously won the rigged ballot." There's no character as "important and deserving" as an obese crocodile who was written out of his own franchise a decade ago.
And it sucks, because K. Rool himself is pretty great. But him getting in means rewarding a bunch of entitled whiners stuck in the nineties and armchair game developers, so the idea gets less thrilling with each passing day. Harsh, maybe, but who cares.
I get your feel, but also have to throw out the reason why so many people are passionate.
I see two communities of supporters in the Smash world. That are very similar. They just don't realize it. At first you might not even notice it.
Those two communities? K. Rool's and Geno's.
Both are characters that were left behind. We lost both of these characters for various reasons and they haven't appeared in modern gaming in quite some time.
And I think a lot of the passion that goes into them is from a stand point of ''Well, Smash opens doors." and that's absolutely true and I can understand why both communities drive forward and keep doing what they do.
The difference however is that one handles it with the utmost class.The passion has not been warped in one, while one most certainly has.
And it might be because one is a supporting role and the other is a former main villain, the truth remains however I have never once seen a Geno supporter throw down and call another Mario character a waste, bring down anyone in their conquest to get this character they loved dearly in one game to return in Smash that in hopes it will push Square and Nintendo to let him become a regular Mario staple.
K. Rool fans should really take note of what they have and remain humble, because they don't. Very few don't. Because they have the world compared to Geno's fans. K. Rool was last seen 10 years ago after many appearances. Geno has not been seen since 22 years ago with just one sole appearance.
So I ask how does one fan base can go 22 years without seeing their character and not put others down? But one has only missed a decade and they feel as if to get their goal and see their fav again they have to bring anyone in his franchise (and sometimes others) down to support him?
What makes this even more sad of a comparison for me? All along the way Geno fans have been picked on for being silly and supporting the impossible in this fanbase. Yet to me they just might be the the nicest community of fans in this speculation community I've had the pleasure to interact with.
But I've ranted enough but I just had to bring up this comparison because I don't think anyone else has ever noticed how similar the situations are and how differently both groups handle their situations.
