Get rid of demolition rune and buff towers

I had a game where the enemy toplaner was using it (i think) and the enemy team kinda kicked our asses. But the game didn't end early. We nearly lost a few times but were able to pull it back. We won with a base race because Yorick. I really don't know what people are talking about. game length feels the same as before.

Is anyone actually using Demolish? I've tried it, and I only noticed about 300 bonus damage. 300 extra damage every 45 seconds after 5 seconds isn't much at all. It might hit large numbers on true, dedicated tanks (such as Sion), but won't do that much for anyone else.

Yorick uses it and its one of the reasons he has a 56% win rate atm, he can clear whole lane worth of towers in a minute span.
