[SUGGESTION] Solution to Early Game GGs
Give all lane towers a 1000 point non-regenerating shield for the first 10 minutes of the game that provide a 50% damage reduction, from all sources, to the tower. This would minimize the damage of feeding early game, but if the enemy focus fire enough on a tower with high attack speed or many source of damage they can bust through. The idea is so you focus on farming and controlling dragon and whatnot early on and worry about towers After 10 minutes have gone by, after everyone has had a chance to get some farm.
Lets be honest, the most fun and exciting games to be had are the ones that last closer to 30-40 minutes so if everyone has a chance to get their "fee planted" then early surrenders would less of a thing and 1 lane feeder would not mean everyone else on their team is doomed.
