Don't worry, fellas. I participated in that bracket, and I can fill you in as well as set the record straight about Dixie's perception in this context.
Including Dixie in the echo bracket was a decision that the poll master made without really thinking, and he regretted it very soon after. Many people disagreed strongly with this decision, and as a result, Dixie did rather poorly on the bracket compared to her true potential--it's the reason she lost to Funky, for sure. The people on Reddit wanted her to have a unique moveset, so they voted against her in the Echo bracket.
The poll master has stated, today in fact, that he will likely make another bracket once the game is released for DLC speculation. This time however, Dixie will be among the Newcomers. I hope I've set some minds at ease here--we are not fighting an uphill battle.
