So, we know that the upcoming Progression server will use the new Spell Research system. What about the system for Jewelcraft? I have two serious concerns which cause me to bring this up: 1) The old recipes produce statless items. Are all the needed items in place to make useful items immediately on Progression? Do the primary gems (like Taaffeite, but lower, as opposed to the secondary gems like peridots and opals) even drop in old world content? 2) I'm not sure that the Trio Jewelry which replaced the old recipes isn't overpowered for content older than Omens of War. I haven't yet gone to the effort of working out the stats at level 50, for example, but I think I have good reason to worry here.
