Infinity Edge on Rengar?
Since the main source of Rengar's damage is autoattacks, wouldn't it be a good idea to get this item? As opposed to various armor pen items, it scales well into lategame. (Last Wisper is a good item too, but it is less slot efficient)
In general, what do you think about build like this:
- Infinity Edge
- Trinity Force
- Boots of Mobility
- Sunfire Cape
- Spirit Visage
- Youmuu Ghostblade
