I got my toes wet with a debate but I feel the site would benefit from 2 changes-
1- Rules on AI should be hard established. Someone agreeing to play a game of chess is not agreeing to play against you while you use AI to suggest moves for you. Just because you pick the move does not make it any less like cheating.
This dynamic exists in debate to the same level- there is a difference using tools to grab data for your arguments vs using tools that give you talking points. I would propose that individuals who use AI should absolutely be forced to declare as much before hand. This issue specifically makes me question debating here.
2- Open format should be allowed with options such as contender picking a side of the argument or having the positions randomized. This would also create incentive for individuals posting topics to do so more fairly and not rig in rules that will put someone in an untenable position.
Also a personal thing- I find it much more fun to debate any position as it demonstrates true ability in debating as opposed to having strong talking points on just one side. It would open up a much more free competition that would reflect who is actually better which makes sense if you are to track a leaderboard. Otherwise I can simply make loaded topics with sneaky rules and blow up my stats which takes away from the spirit of what the site is going for.
