i don't play smash 4, so i can't really offer much discussion as far as banning bayonetta.

This reminded me of when Unity Ruleset in the brawl days wanted to try banning Meta Knight for a set period of time (especially considering a large portion of the ruleset had straight up changed or had rules added because of him). One region complained about how it was bad for the scene to ban this character because it was unfair to people who mained MK, and ignored the ruleset. After that happened, people treated Unity Ruleset like a joke, and soon after the meta became a lot fewer stages, more meta knight, and suddenly more ice climbers now that there were fewer counterpicks against them (A lot of the stages that MK was crazy good at, IC's weren't as great on. More stages banned = fewer varied stages = ez ice climber cg's). Unity definitely was a great idea at the time, but there were for sure a lot of flaws that it had that could have easily been improved. I only wish that people had given it a chance and worked with it instead of just shoving it aside because of one region.

I feel like this was a contributor to brawl dying out that a lot of people tend to forget, aside from PM/Smash 4 being released.
