You know what buff towers need?

Attack speed. I've said it before and I'll say it again. If they attack faster it won't affect your ability to CS under tower unless your attack speed is slowed. It will prevent dives, early pushes, and draw out games longer. Look at Twisted Treeline, those things aren't fucking around. They'll shred you if you tank them. I want to try my 1,000 AD Malphite in that map just to see how long it takes to die.
