Hmm, it might look a little weird, but I think this could work as an avatar.
It sounds like part of the reason why some support threads have been particularly volatile recently is because of the dearth of new Smash info. We don't even really know when the next batch of new Smash stuff is going to be announced. What we do have are a bunch of rumors and text "leaks" that seem to provide just enough info for people to react to a hypothetical scenario where a character they like doesn't make it and one they dislike does.
I mean, I definitely support K. Rool being in Smash, for example, but I don't really care for posts complaining about "anime characters," criticizing Dixie, or trashtalking Daisy, Shovel Knight, and Shantae supporters. I think I sort of understand where people making those posts are coming from since there are only a limited number of spots for ballot DLC and K. Rool is quite popular. That said, I feel like it makes sense to focus on supporting the characters you like now and then see how things go once we actually get an announcement from Sakurai and co.
