I've said this before somewhere but hosting the same tournaments each month honestly starts to feel like a chore for the host. Remember, the gimmicks are a break/alternative to regular tournaments for the hosts too and are also a chance to show some creativity.
If WND/SNH/FNF come back that's great, but they're quite draining to host. Getting enough people together on roughly the same day each month is tough as well. The only tournament that has been consistently done for over a year(mostly) is TT, which I'm so grateful for.
Edit: Just realised it turns two soon! Thanks to everyone continuing to host that event among all the other events that are hosted each month.
