Different game modes in custom games
These days, the best way to get my friends online to play League, is by doing custom games. Either 3v3's or 5v5 custom games on the Rift or the Abyss. Seems like we all have the most fun with that sort of thing. Why not add more options to custom games? More game modes, game modifiers, ECT. Seems like a no brainier to me.
