This may have been mentioned before.

I think it would be fun to have an elimination type game mode on Summoners Rift.

Each player chooses 5 champions but each champion only gets one life. When a player is defeated they continue with the level, gold and items they have but spawn with the next champion in their list.

The first team to destroy the other teams base or eliminate all the other teams champions wins.

I believe it would add a whole new layer of strategy and team play.

This would require having at least 25 champions unlocked before you play Blind Pick. And 50 + Bans for Draft Mode.
