Yea these methods for making meseta have always been standard for base pso2 as well, but you may eventually get burnt out quicker, than enjoying the game or playing another game... or exercising, hobbies, etc.
Yep, the only thing I can think that will regulate the auction house is; AC items can only have 1 transaction. That way, people that want to buy the AC item, will use it. For example, I buy AC, scratch once, and list the item, once someone buys it, it's bounded to that account. As for non-AC items (for upgraded gear) if a player enhances or affixes or both, etc. then the item should become character bound. This way SEGA can also allow transactions for those items to have 1 transaction count, but you can purchase a Gear-Unbound Tag (maybe for 200 AC), to be able to list those enhanced/modified player gear to the auction house. There are many creative solutions, but those are some I thought... Are there better ways? or what do other people suggest?
