There really isn't a barometer to gauge community interest. For instance, Deku VS Asta (lol) was seen as a popular alt for a time but by the time we produced it, Asta VS Meliodas was the big boy around and now everyone hated VS Deku. It's kind of hard to gauge opinions when there's so many and there isn't one common consensus. Personally, I think SimonKyle, BowserEgg, AshYugi, and Omnidock all were massive hits.
I think if it was a case of we don't listen to the community, then Simon VS Kyle or Ash VS Yugi wouldn't be fights we pick as those are massive commitments to make to do justice. Oh, and on the other hand, I did see that "they need an inside community guy." For the record, I pitched the Champions Poll, Tournament of Champions, did all the assets for them, and help run a ton of the recent community events. I'd like to HOPE I'm listening to people.
As for Kaiju, idk what's the big one right now? lol
EDIT: and to preface, MY opinion, not the team's
