Guys he isn't talking about making money on the ah. He's talking about the amount of currency generated by the game that enters the game world. When you buy something on the AH money is not being generated, it is changing hands, minus the 5% removal. This means that if everyone is using only the AH then eventually there will be ZERO currency left on the server. What the OP is referring to is that there are very limited ways in which there is a SUSTAINABLE GENERATION of currency in the game. This means that the only solid way to GENERATE currency (to any amount that is) is from selling allagan pieces garnered from quests. Once a person, and every person, on the server for that matter have completed all the quests there will not be a sustainable influx of currency being generated and there will be inverse inflation happening until there is eventually very little currency (repairs and ah cuts being a large factor of this drain - player housing when its implemented)
