Rework Ohmwrecker and change tower play with that?
Ohmwrecker is useless, was useless back then and will be useless since towers aren't worth it. What if we take Ohmwrecker and change the effect completely.
Active: Buff a Friendly tower.
When I say buff I think about something like damage increasment for 15 seconds, higher fire rate for 30 seconds or anything like that. Maybe Ohmwrecker could even have different actives (here i would like to ask you for some great ideas) which you have to chose while buying. Like a generel start item and 3 different paths to complete one.
It would help a Item, give the game a new defensive strategie and towers (which we don't like since .. long?) would benefit from it also.
Here's my 2 cents. Gimme your dollars now.
