Changing Rapid Firecannon for melees.
I know that the item isn't really supposed to be picked up by melee champions, but what about a slight tweak? If you're a melee champion, then instead of the extra AA range on the next AA, it could be this:
"For the next X seconds after you trigger the effect, you gain Y AA range."
So, the duration could be 3 seconds for example, and grant the initial bonus range, or a standard 150 range. It would be kinda like a mini Aatrox ulti with the extra range for the next 3 seconds. It could help them stick to their targets for a bit more before getting kited to death.
