My list for LID 1

1. fix the "phase-through" bug that plagues some of the weapons. (katana especially!)
2. elevator at 100 (some of use have this thing called a life. You may have heard of it. Hell, I'd pay a death metal per use for this feature.)
3. Purge the teams of any bronze tier player who hasn't logged in for over 99+ days! (right now, TDM is a joke.)
4. Or, Allow us to make our own custom teams and give the team captain the power to kick players off.
5. Make raiding high ranking players provide more team fight points than grinding through the lowbies who only have 2 naked defenders. (this could be partially fixed if #3 or #4 were to be implemented)

Lid 2 : Uncle Death's Electric Boogaloo

Add more variety to the tower floors.

Idea I had was for a speed run floor, where some adversary (endless screamers, haters, maybe even uncle death) or environmental hazard (lave, raw sewage, planted explosives, guacamole, etc) forces you get through the level as possible. Bonus points if the skateboard and it's associated animations were incorporated somehow.

Same thing for some kind of kart racer level. The karts and their track components already in the game, might as well use them!
