Just Make a Team Deathmatch Mode! It's Genius!
For all the people who complain about too many people mistaking LoL for CoD, the solution is ingeniously simple.
Just make a Team Deathmatch mode!
That way, the people who just want to kill stuff can kill stuff, and the people who want to play an objective-based mode can play an objective-based mode.
Shoot, while we're ripping game ideas from CoD, why not throw in a Domination mode? Teams fight to control 3 bases on the map. Controlling a base gives you points-per-second. The first team to reach a pre-determined score (I dunno...150 points?) wins.
Hell, even better. Free-For-All. Legit 1 v 9. 10 players enter, only one can win.
Let's just go all the way with it and introduce a Kill-Streak system (to those modes).
3 kills in a row? You can see the minimap.
5 kills in a row? You get a Cloud Dragon buff.
7 kills in a row? Infernal Dragon buff.
25 kills in a row? Umm...what's the equivalent of a nuke in this game? Baron + Elder Dragon buff and a Karthus ulti?
Create a game mode that's like a fly zapper, luring players that don't want to cooperate away from cooperation heavy game modes.
Just spit-balling here.
