I would miss both the professions, though they aren't what they used to be. There have always been those designs and formulas that made me go "huh?", but there were plenty of others that offered a semi-realistic benefit at the very least. I used to see demand on my server for all sorts of cuts and enchants. Now stats have been removed or homogenized; I think that the latter is the major contribution to the de facto "optimal" choice for PvE.
I personally would like for item level upgrade feature to go away forever. If I have to go outside of the game to look up what the final version (last item level upgrade, i.e.: 2/2) of a piece of gear will be in order to make comparisons, then I think there is something wrong. This is not to say that I ought to be able to look at gear for my spec and say upgrade/downgrade in under a second, but that I do not want to agonize over item-level upgrade vs other gear piece (from somewhere) vs vendor gear piece plus reforging on top of everything. It's too much for me. Maybe if I didn't have a low ceiling and/or cap on JP and VP, I would not be so concerned about risking what I've managed to accumulate.
As a side-note: Stay away from my racials.
