Change the timers on IBG for ranged champions or at least something for them

30% AOE slow on a ranged champion is quite abusable. Especially with its 1.5 second CD. I can understand that for melee, but ranged makes it way to easy to proc, since it is ANY target hit, not just champions. That means an EZ can shoot his Q wide, hit a minion and you still take the full slow and bonus damage.

Any of these changes would help out (these are only for ranged champions who use this item)

1. Passive applies the slow for 1 second available every 3 second
2. Passive slow and bonus damage only work if it hits a champion
3. Passive slow's CD is 1.5 seconds if the ability or basic hits a champion. If it is not a champion, the slow's CD is raised to 5 seconds.

Any of these are workable since they do not deter from kiting away when being chased, but stop the super aggressive chasing/zoning by already mobile and/or super safe marksmen who are balanced around not being able to do that to this extent.
