New type of game mode
I was thinking we should a "horde" type of game, where you fight hordes of minions. Having the setup like one side of the map, and then other being "minion territory." Start with the usual amount of minions then gradually increase number and type of minion, i.e. start with just melee and ranged then add the tank minions, then add super minions. Make it a survival game, starting with gold and levels like dominion so it is fair from the start.
. Others would have issues
though it would be fun
