Nokaled: We're still experimenting with the modeling. It is probably good. It is probably not quite as good as its currently showing up. No one is going to be able to tell you anything more than that for the time being.

Addendum: please stop asking about the aforementioned 3 items. Thanks.

Basically: we're still working on getting the modeling right, and due to time constraints by all involved developers, it takes time to develop fixes to issues as they are discovered, and time for those fixes to make it onto the actual website. We're doing the best we can. Please be patient.
