Game mode idea: Team Death match

This is a pretty basic idea and it could even be accommodated on summoners rift. Remove the turrets and objectives from the map, or at least disable them. Thicken the fog of war. Remove Minions and Shopping.

Start everyone at level 18 and adjust them for balance and let them go at each other for 25 minutes. Team with best KDA at the end of the match wins. Make each jungle camp and bush a random spawn point so that someone that is doing exceedingly well does not just camp your spawn point with cc or burst damage.

I mean it is a crude idea at this point, but it would be kind of fun and a good way for people that flaunt their KDA to make that mean something.

Any one like the idea? Have means to elaborate upon it?
