I was unhappy with the cap initially as well, but seeing the system that they designed I don't feel that more than 2 or 3 classes capable of desynthing are needed. CUL aside, only the objects you can desynth are different, not so much the results. Sure there are primal weapons/ accessories to think about, but given the gil sink that desynthing is, I'm glad that my GSM can get most everything out of this system and perhaps I'll level BSM in desynthing as well. The only hurdle imposed by the restriction is that you can't desynth EVERY item you come across. You have to plan accordingly. This is most relevant with primal weapons, which I suppose is a huge sticking point for some, but I personally have little interest in that.
