The system is by far the least interesting "forced cooperation" system I've ever seen in a game. There's nothing interesting about it at all; the recipes only exist to save face for whomever designed the specialist crafting system, because nobody uses the skills at all.
I don't want to have to worry about "which specialist should I choose" before realizing I've made a huge mistake and can't switch without giving up more than 1 week of my life in red scrips. That was the whole appeal with DoW/DoM leveling in this game, that you could do anything, and if you wanted to switch you could.
