Can we add an item that increases cool downs?
We have Frozen Heart and the like to deal with attack speed, armour and Magic resist to deal with respective damages, so could we have a global item that increases Cool Downs within a certain radius for enemies?
A cool down increasing version of Frozen Heart might be just the thing to stop champions who are usually unphased by most itemizations.
Maybe a 5%-10% increased CD to enemies within a radius?
