2000 gold buff potions?

If anyone played Smite, they have these really expensive buff potions for use when you're max items and sitting on a ton of useless gold.
I think it would be cool if we had potions like that in this game.
Stronger than the current ones we have, but much more expensive and a less gold efficient.
So they'd be used strictly in very late game. And getting kills and whatnot still gives some return when you're maxed out.
