I don't think people are taking into account the accelerated wave/jungle clear that 10% gives. That is where the real snowball is. If I can clear my wave to your tower then run to help my jungler or other lane, since this map is so compact you either defend your tower while trying to make up the farm, which will take more minions in the first place, or chase me and lose farm while my minions got to town on your tower. It's a lose/lose proposition.
