Changing Ohmwreckers Identity with Towers

So far, Ohmwrecker isn't bought too often as it usually isn't nessecary to disable a tower as they fall like melted butter. What if we changed it from disabling turrets to granting allied turret resistances for a brief moment?

It would be nice against seige comps, or anti turret champs like Tristana. It could even be helpful in stalling losing lanes like vs Tryndamere where he just farms and pushes.

Its mere activation on a turret could make a seiging comp back off, giving your team a chance to either attack or position better to defend.

Thoughts?
