I think any% hard mode would be a great category to add. I also like the idea of keeping the subcategories for each squad, it'd be fun to see runs with slower and "Worse" squads like Steel Judoka be represented and ran, I would love to see it at least.

I think the no ice artillery category should stay at least for now, if new strats come along, and the community develops more so that the distinction becomes archaic and weird then it can be removed in the future. At least right now it seems like such a dominant strat that it kills the category without that distinction (although the argument can be made that other strategies can probably kill the category too). I think it's good for now though.

I also think an any% non-custom squad category is something at least worth discussing. Even if 99% of the runs are frozen titans or something it would give the people that don't like subcategories a board they can focus on and like. Maybe in the future different strategies are found as well who knows.
