The missions for the crafting should be based on the zone you are in, not based upon your skill level. Same for your hirelings - they should bring you mats you can use rather than what your skill in that craft is. I do want to say thank you to my hirelings who stocked me up with all that nightwood & voidstone ore while I was VR5. I had PLENTY of stock when I hit VR9!
Speaking of which, I couldn't make a thing when I was VR8 because I was a level or two higher than the PvE zone I was in and all the mats I could get was one level above me (from my hirelings) or one level below me (from the PvE zone).
The hireling mats should be player level based, not skill level.
