Back Up Plan
Everyone hates to feed early in the game. No one likes to fight a losing battle. Everyone hates it when the fun is over when the team you dominate surrenders early. So why not give the losing team some backup? Some sort of buff or backup minions to give some slight help in getting them back on their feet. I really hate having to over dominate the team to the point where they surrender, and of course the other way around. Some sort of back up plan to help the losing team catch up basically.
