I would definitely take mining as one profession - mining nodes will not only yield cobalt/saronite/titanium ore, but crystalized earth/shadow/water/fire and occasional gems as well. The +50 stam is great, especially for a tank, and the ability to smelt titansteel once per day is handy.

Other than that, I'd look at BS for the ability to socket wrist and gloves (which stack with enchants) over JC, since 5 rare gems > 3 prismatic gems (even if prismatics offer a bit more flexibility in where you slot them). BS will also let you socket belts for everyone in your party, and your alt druids might like Titansteel Guardian along with the Prison Manifest (BoE drop)... and of course there is the tanking gear that you can craft.

JC's ability as a money maker is dwindling as more JC's max out their recipes and then will only be able to change their tokens into dragon's eyes instead. And since the patch, dragon's eye's also drop from these - Ice Prism (they also give 3 rare gems) - soon I would expect the price of the eyes to drop well below 100G...

Cheers,
