Why do MMORPGs go live with serious bugs or seemingly half finished? I know the two obvious answers $$$$$ and supposedly certain bugs only show up after release.

After the disaster with Vanguard a game thousands of us were hoping to be a real advance over EQ and WOW, you would think that AOC would have this finished and bullet proof. What the Hell is Beta testing for if not to prevent this kind of crap?
What is this about proposing major changes just weeks after release??? Like they couldn't figure this out in beta?

Bottom line is this.
EQ was the gold standard, instead of putting all there money in to enhancing EQ the dumped it into EQ2 at the time WOW was launched. WOW was more fun and at the time superior to EQ2. WOW sucked all the air out of the Room for MMORPGs. WOW became the model more fun less grinding, less complex, less grouping=more subscriptions.
It will take an MMORPG that is significantly different and polished from day one. It will require a paradigm shift and new concepts i.e. a visionary genius development team to break the cycle of EQ clone WOW wannabee failures.
