Here are a couple improvements I've heard/People have suggested
~Don't listen to Glenn and do Double Elimination
~Speed up the game
-Different Power Weapons(Rocket Launcher(Knockdown only, 50 Damage and knockdown, etc), Molotovs, etc.)
-Limit Ammo(5/10 shots)
-Maybe Spawn with 1 shot, can pick up additional shots from ground
-Increase Team Sizes and composition
~New Maps
-More Contestable power weapons
-Prevent shots from spawn/make them more difficult
-Enlarge Map/More Routes to outflank camping
I think most of them are good and I've hear a lot of positive feedback from people so we're probably going to try to have another one of these tournaments with just a bit less camping
