Well, there's a bit more to it than that. Specialists will have access to unique skills which may make crafting a lot easier than simply cross-classing everything. After all, there needs to be benefits for players who have already got every class at 50+.

However, none of this really matters. As mentioned, part of the scrip system will allow you to swap your specializations so it won't be a permanent choice if you don't want it to be.
