I think it would be logical for a global re launching of aion classic since 1.2 with tweaked open world drop rate ( in the past they took measures towards bots) , now I think the wisest is to hire admins to actively surveillance towards bots , cheaters , ap traders.
It is pity that we have only 1 server of classic that is not longer "classic " anymore by any means , this re launching is mandatory to preserve the comunity interested into the game ( the population of aion classic is decreasing and that has been happening for patches already) , I am sure that you will spark the interest of so many players by launching it well made and thought with proper measures.
