titansteel is imo not going to be a great moneymaker -- the price of xmutes has gone from 100g on my server down to 30g last night, the price of bars has gone from 500g to under 200g in a week. This is on blackrock though which is a high pop high end server (like 20+ guilds clearing Naxx25), frozen orbs sell for < 20g now. What is in decent demand is dragon eyes, so imo JCs are the most "valuable" profession at the moment.

and imo the titansteel mace is great for shamans, the shield is great for the tanks. The rest of the BS crafted items are weak for tanks, I wouldn't bother with the helm/boots/legs. The JC neck is very weak for casters and tanks (the tank neck is a joke, you can buy the Burning Pendant or whatever on the AH for 30g and its better in many ways). The ring is decent for casters, the tank ring is not great.
