While I think the title of your thread is not constructive at all, you do have some god points.
1. Aeria, no action on goldsellers/goldbuyers
Honestly, I can't say what GM's and other Aeria employers are doing against it. Sure they must be doing something, but it's not less true that they actions have a very little results.
2. Aeria, overpriced item shop with a ladder/event every week to sell
That's not an issue so far, since people with high acquisitive power can and do afford those items. Could be better? I can't tell, cause I'm not an expert. I'd be willing to pay Aeria for products if I feel more respect to middle class coming from the company? Probably.
Same as 1.
4. messed up economy
Appart from the bot/goldbuying problem, there's just not enough offer. Only few rich people can afford to get the cash items. Even only a few of them can get em, since the odds in a gambling systems are always naturally as low as possible. Anyway, as result of that, low offer, so higher prices, plus less and less population cause all we're statin.g
5. market controllers (fairytail guild, twerp etc), buy all of one item raise the standard
Something should be done against especullation, indeed. For example, unbind counts for gear and synthesis goods (mechs and skins), and consumables, enhancement tools, etc. NON TRADEABLE after puchased from AH, like in other games like Vindictus (at least the European verion, were market behavour and prices are just like being in heaven.)
