Demolish/Rift Herald/Mountain Drake/Baron causes Ohmwrecker's active to be far more useless.

I don't think it's been meta in...4 years?

Whenever you use this item the tower is either:

A - Dead in a few seconds anyway

B - Being tanked by somebody with HP/armour

C - Neither, and even at that you're probably not saving anybody because people would never reasonably rely on somebody to use Ohmwrecker.

D - You actually beat the odds of everything and find a use for it. Congratulations, you successfully used Ohmwrecker's active once.

Just butcher it and delete it. Change it's passive. Do something god damn. I, personally, would double down on the point runner passive where you get normal point runner, but + 10 - 20% more movement speed inside either team's base stacked on top of walking near towers.

I won't even bother looking up stats for it because I bet people only buy it while winning a game and just messing around.
