What if we gave Ohmwrecker offensive options?
-So right now
is seeing little to no play, but if it could be used offensively and defensively I feel like It could be a more lucrative buy. I don't know if this will help Ohmwrecker but I think it's worth considering. Ohmwrecker always had a reputation of being the "Interacts with turrets" Item and this will only solidify that idea. Plus, turrets are incredibly underwhelming at the moment.
Below are some ideas that I had for the offensive ability of 
Just to clarify -Ohmwrecker will still have the ability to disable enemy turrets -The same turret cannot be Ohmwrecked (this is the official term) after the buff has been applied until a certain amount of time has passed -I'm sure my numbers are terrible but this will give a general idea of what will happen
Version A:Shaped Blasts -Towershots now deal increased AOE Damage -This will help to clear waves and discourage the enemy team from diving so that your team can have a few seconds to prepare by buying items or healing etc.
Version B:Plasma Beams -Towers gain a laser upgrade, increasing the damage of lasers and giving the tower ramping Armor Penetration and Magic Penetration -If it is not a laser turret, it will gain an additional laser alongside it's tower shots -If it is a laser turret, it will gain one more laser and both lasers receive the upgraded effects
Version C:Overclock -The turret rapidly fires 5 towershots that each deal 3% HP damage in both Magic and Physical Damage (Each shot will deal 6% altogether neglecting resistances) or -The turret gains increased attack speed and damage
Version D:Plasma Burst -The turret charges up for .5 seconds, then gives off a large AOE burst of damage but becomes inactive for 3 seconds after using to all enemies and applying a 50% slow that rapidly decays over 1 second
Version E:Guardian -The turret gains a shield equal to 70%+(Player Level) of your HP that decays over 5 seconds
