It’s definitely not worth dividing by resources. Tournaments on HeroesWorld and the League have been held for quite some time without any issues, so I don’t think anything needs to be changed here. Some people even manage to play the seasonals on the Portal — well done, I tried, but I physically can’t play that much.
I’ll support Yura, I also liked the team game — maybe implement themed team games on HeroesWorld? As for regular tournaments, the League is enough. By the way, it’s been a while since we last had paired tournaments — the problem might be with the templates, but I think it’s solvable, the main thing is to get started.
