I get the feeling this kind of discussions wouldn't crop up as often if the devs would just post a development roadmap: they should just keep a public list of the things they plan to do, along with reasonable time estimations for completion of each feature.
I mean, this is what happens in most dev projects. It would help people be more patient, it would enable everyone to see that yes, development is still ongoing, and that they can expect such and such feature by a given date (more or less).
As for now, it seems like a guessing game: are they working on the AI ? Other things ? When will the next patch be released ? Having a public roadmap would help a lot.
