Yeah, the normal exp you get/price of gods are absurd at the moment.
There's no way snowballing is significant. You have to screw up SO many times...with 400~ gold a god kill, you have to die to them SIX times for them to get ONE fully upgraded item. And even with a whole item advantage, they're still very killable. The exp bonus only nets them like...2 levels as well. It's laughable.
