I dunno, I think a lot was wrong with Aion and Warhammer: namely, sticking way too close to other games in an attempt to somehow beat them by doing what they do, better.
There's more than one way to do a MMO, its just up to the company to decide what to integrate from rivals and what to self-improve on. Aion integrated waaay too much from WoW, other Korean MMOs, and other F2P MMOs. Its a hodgepodge MMO without its own voice as a result.
If nothing else, I can say that FFXI had its own, unique voice. It was grating at times, and sometimes sung off-key, but it was unique in of itself.
