I'm only concerned about the banning of Crimson and Danger zone. Right now, there is probably a good number of people, myself included, who don't have a new gen system yet and can't make a budget for the game and have to wait for a while. I also hold casuals regularly in my local scene using my own system, so essentially I might end up two stages or even two characters short. That's fair. I'd rather pay my mortgage and bills and as long as someone else gets the new system with all the content so that people can play and particle on.
But, if the two stages are not banned, then I'd have a bit of a hard time deciding whether I'd enter a tourney or not since I'm not confident and familiar with the new changes.
