My JC follower is ilevel 645 Olin, too busy getting me loots from Highmaul. I think I might have to roll out another JC follower from the inn. :/

Yeah pretty much this; (versatility gems sell for 50% price though). Main issue I have is the sorcerous airs; Any way to get more of these?
As for the daily I always wait for the ore ones or the ones that use true iron ore.
The daily is offered by a follower that's assigned to a level 2 or 3 JC building. The profession Jewelcrafting has zero effect on this. I'm placing a JC building on all alts for the extra ~200 gold per day. All it takes to craft the quest items are ore and occasionally a few herbs, both are more than plentiful enough.
I only clear the mines on my level 100s and my stockpile just keeps growing. 4k+ Blackrock and 3k+ True Iron. Not even clearing the mine for the ore, but for the chance to get a goren to spawn that has a chance to drop a pet.
I'm also at a point where I don't re-fill work orders for the JC building. Got so many of them and selling the rings/amulets can be a pain at times.
