I disagree and think that they have learned a lot. I don't expect a game of this quality and complexity to come with a toolset like NWN1. If someone released a game like that today, I doubt it would make the money back that would be required to create something like it. For better or worse, expectations are higher for graphics and other gameplay features. Given what DOS:2 can do, this editor is quite remarkable in its balance for accessibility and flexibility.
That said, Larian have made huge improvements in being able to do most things from within the editor. Stats editing, dialogs, journal maintenance, and several other areas have received huge quality of life improvements. They take a little time to learn, but once a development flow is established, it begins to move along nicely.
In addition, Larian had an early access period where they paid to have modders come visit their studio and provide feedback. They have created a nice infrastructure for building up a knowledge base, and we have already seen them here posting a lot to help the community get going. The tools were practically available on day one and we see way better traction at this point than DOS1 ever did. Larian have learned and accomplished a lot. While there is always room for improvement, let's give them the proper credit that is their due.
