I don't know, I don't feel like it's that horrible.
You have to use Ctrl-Shif-F search to find the info you need, but in the end I always find what I need to know.
Compared to the ArchiMate specs I think it's even much better. Based on the UML specs you can say, without a doubt, that something is allowed, or not. (almost mathematical)
When you try to do the same based on the ArchiMate specs you only get to "yeah, probably, maybe, looks like it."
