GP adjustments

Would it be too hard of a hit to nerf GP's gold generation mechanic? I understand no one wants to touch his damage anymore, and TBH i have no issue with how much damage he does late game. It's very conditional and can be prevented by a variety of ways. My concern lies with how Early he is buying the games most expensive items. Buying expensive items is why his damage is allowed to be so high, but his gold generation is getting him the most expensive items in the game way to early.
