Honestly, I don't think its fair to write off DQX just because it's an MMO. All of the reports from the beta testers (of which my friend is one of them) have been pretty positive. The general consensus is that it's basically a better version of DQIX. Better story, better environments, a lot more robust and full of content.
And in any case, an MMO is something Horii has been wanting to do with the series since around 1999-2000, so it's interesting to see how that's actually panning out
