Actually the opposite will happen - AI armor costs a lot because the demand is high and the supply is low. Adding instanced cities increases the supply, lowering the price. In particular, it allows people who used to have to go to farmers to buy bots to get their own. Farmers lose out, average players win. Of course some ppl will still just buy what bots/armor they need but a significant % will now go get their org an instanced city and get their own bots...as well, I expect to see quite a bit more competition among and against the traditional farm orgs.
