Barrier to entry being way too high is the reason I think that SE has taken, and is taking, the wrong approach to crafting.

I've said it before, and I'll say it again. Get rid of the Specilist-only flag on recipes. Get rid of the current Specialist-only actions. Make each Specilist stone give the 21 cross class skills, as normal skills, that the other seven crafting classes get at 15, 37, and 50. Tack on the 54 cross class if desired (my original idea was not to tack on the 54's until the level cap goes up again; but seeing 2 star and 3 star they would certainly be valuable).

That would allow someone with only one crafting class to make anything in his crafting log, without feeling (or being) forced to level the rest of the classes for the cross class skills. It would put a single crafter in the position of having to source his refined materials, but that disadvantage would be balanced by the work an omnicrafter had to put in to become an omnicrafter.
