I think pointing to the things that NWN/2 did well is useful, but we also need to keep our retrospection even handed. For one, that book you posted gets pretty bad reviews.
What's more, for whatever spectacular longevity the NWN community enjoyed, the game itself was not a long-term financial success. I think Larian is on the right side of the divide here and with the right priorities. The toolset team is currently focused on the things that we as a community can't do, like adding features, fixing bugs, and documenting some of the more technical parts of the system. For my part, I would like them to stay focused on the things that are hard for the community to do and we as a community take some initiative to get others up to speed who are showing interest. As SniperHF alluded to, we can do a lot to capture the imagination of the early interest by giving them a foretaste of what the editor can do.
