Turrets could use more MR...

With the change that turrets now take magic damage based on AP (I forget if AD contributes on champions like Akali that build Gunblade), AP is extremely efficient as it is and makes turret taking as a mage or AP assassin/bruiser too easy. I get it means that mages can contend with AD laners for plates and first tower, but as the game goes on, it's actually funny seeing AP champions chunking turrets like crazy.
