They started in that direction with the moves every crafter learns from 61 through 70.

Personally, I believe that Specialists should get access to *all* the cross class moves, 15, 37, 50 just for equipping the stone... and the 54 cross class moves once the Specialist hits 61. That would have done enough to actually accomplish what they said they wanted to do with Specialists when they introduced the system (allow them to compete with omnicrafters).
