TBH, FFXI-AH will not solve any problem we usually hear in ARR, If someone will have very hard time with ARR MB,
most likely this person on FFXI-AH will not know he had been undercuttered and he had over-bidded, and frequently. ^^;

Moreover, FFXI-AH wastes a lot of time to test the lowest price, and it is easy to input wrong bid, for example, add one or some more zeros, to bid an item and ofcoz, you won the bid immediately. Even I think it is buyer own responsibility but many players will still call GM requesting for 1time restore... ^^;

Another story, in FF11 one day i bidded a belt for 25K while last sold 50K (for exmaple), then I went to level up party, and then 2 strangers popped and kept following me and asking for refund. This was one of my worst FF11 experience^^;
