What I heard (did not see anything from SE or Yoshi themselves) was that they are revamping the combat system, removing less-/un-used skills, and changing some cross class skills into role-specific skills.

Last I checked, while they are not combat roles, all of the DoH share a role : crafter. Just as all of the DoL share a role : gatherer. If they nix cross class stuff and just make the formerly cross class skills role-specific skills, that may help those crafting classes that simply don't have enough room for everything in their cross class skill section. I'm thinking of BSM here, but there are others that are forced to make choices.
