This happened in FFXI as well, jeuno was the major place to be, the center of everything happening. I havent been on in a month or so, but one thing they changed was linking all the AH's together. So you didnt have to go to Jeuno to find the best price or items you needed. I believe if this was the first change they did way back when FFXI first was released, it would help other citys survive. But with FFXIV, its hard to say, i guess my only idea (maybe not the best) but to allow you to choose 8 more leves in each city. Keep all the rules, but each city will allow 8 leves each reset. Might bring more traffic to them?!
