An MMOG requires a lot funding and knowledge, but aside from that it's the same as with all other game genres: Developing it is the responsibility of the user. All we can do is providing functions in the engine.

All network functions are well tested and guaranteed to work. When you have a certain technical problem with an engine function, ask us and we can help. But we can't guarantee that you can finish your game or that it will be successful. That's outside our possibilities.

I can understand your frustration and anger when a huge project fails. Sadly this can happen and does happen with MMOGs as well as with other projects. It's easy to blame the engine then. But I don't think you can tell us seriously that you're developing an MMOG for 5 years, and have not noticed all the time that the engine you're using doesn't work.
