Turrets =/ Fountain

They're an offensive deterrent and once players can circumvent that it stops being a deterrent, which is a natural progression of the game. If you speed this up by feeding, staying around when you're too low, or picking a champion that cannot stall under a turret, then stop blaming the Turret, it was your fault and always has been.

Turrets are there to stall minion waves, not teach you math.
