To be honest I think my main problem is the simple fact that some of the gold suppliers (I'm not suggesting all of them) use hacked web sites, trojans and gain access to accounts via keyloggers. If I found all my hard earned aion gold disappearing from my account I'd be upset to say the least - so there's no way I am going to have anything to do with that sort of practice.
So what to do well I think I found the next best solution to actually having to buy aion gold - I bought a guide that shows me the legitimate ways that these gold sellers farm gold in Aion. It worked and by following the instructions I made some serious gold part time in a few days. The method bring returns that I didn't get near grinding using my own methods.
