I get that, but I disagree with the all or nothing approach. You can have maybe one or two. Smash 4 had Dreamland legal with Battlefield and Melee had Battlefield, Yoshi Story and Dreamland. I don't see why stage strikes are a big issue now. Easy solution would be to try and limit how many of the Battlefield gang can be on at the same time but otherwise allow them for play."I ban Battlefield!" "Okay, let's play on DL!". That's the issue (and grouping is bad, either keep them legal or ban them, no grouping).
