Last Stand game mode.

Would be great to have a game mode where you are protecting the nexus against waves of minions. The waves would get stronger and larger with each wave. Normal minion at first, to super minions, magic proof minions, baron buff boosted minions, dragons, even make baron burst out of the ground near the nexus to attack players , Add champs to the minion wave, and even maybe doom bots. Making the last level virtually impossible to complete. :)
