I originally disagreed with this opinion because I was concerned about the playerbase splitting, but the more time I spend talking to and being around less active players, people would play CTWW way more if it wasn't for the brutally difficult CTs that CTWW fans keep voting for.

I really think if Rule Voting would resume development, all these issues would be fixed and there wouldn't be separation among the community either.

I don't really think it's gonna separate the community tbh.

I don't see how it wouldn't. The community is much smaller compared to other gaming communities. A prime example is just the inacitivty of Countdown. If they keep adding more search options, it'll get harder and harder to find players online. MK8 even has this problem.

Countdown hasn't split the playerbase, it's just dead. There are so many cases of players quitting or losing interest in MKWii because of the elitism surrounding old CTs.

What would Rule Voting do to help, genuine question

It'll allow more opportunities for gamemodes/character & track selection. It'll switch voting to a democratic system. So if the majority of the players in the room want X, X is more likely to get chosen.
