Creep gold used to be rather hard to get and at times was more valuable than freep gold.
With ROI, however, it is ridiculous how much gold you get as a creep.
So why not introduce better ways for creeps to use gold rather than simple pots or trackers
1. Better, MUCH more expensive vendor options? (better be pricey)
2. Ability to buy perks similar to those offered by DP? (not likely, as it would jeopardize the TP store)
3. Transfer money to freep (however, might create more gold farmers)
4. Auction house!?!
5. Maybe buy maps? At prices like 100g for a good map.
