Ohmwrecker, a possible fix.

ohmwrecker is a nice niche item... except it's doesn't do a good job. the problem? it has a binary pattern. or it's useless against turret, or it make turret's useless. but not any more, with this proposal for passive change to: deals [x . (y . user level)] damage per basic attack for the next Z attacks against turrets. and if you make it a niche Ap with Armour siege item, would be better (not for ad users). Yes is a short text, and I not gonna make it a "wall" explain why is a good Idea. But please, just think for a few minutes about it.

if you still wanna a sort version, where it's: > ohmwrecker now deals [[x . (y . user level)] . ToD} for the next (Z . amount) basic attacks against turrets

P.S.: ToD means Type of damage.
