Towers need armor pen to stop bruisers from diving like tanks

Hell when I played akali and built seekers i could tank 5 or 6 tower shots for half my health. I don't think the ability to dive should be removed but it should have a risk/reward relationship for people that shouldn't be doing it.

Side note: there's a video out there of what I think was a TSM game where nautilus tanked 31 consecutive tower shots and still survived. They were the nexus turrets. Riot should consider buffing those as well.
