Ohmwrecker
How about we make it so Ohmwreckers active can work on allied towers as well? Make it so allied turrets can't be attacked for the 3 seconds, same as it's active duration now, and have the same lockout so it can't be stacked etc. Feels like it would make sense without really being broken.
I was just thinking of this the other day. If you're ahead and diving, it's a great item, but what happens if someone screws up and now you gotta def for a while? It's basically a wasted slot without its active. Just a thought -shrugs-
