Profession Switching

I'm currently Blacksmith/Miner.  It isn't the worst, but it generally sucks.  I get two extra gem slots.  I got no craftable weapons for a hunter and no craftable mail (unlike in Vanilla and Burning Crusade).  I hardly ever mine.  I don't ever have my detect mining up because I've left my improved tracking off once or twice before.  So, Blacksmithing really just gets me some stamina. Cataclysm's Blacksmithing weapons are all BoE.  The same with Leatherworking.  Engineering however looks to have some fabulous ranged weapons and of course the helm.  They also have some gem-like stuff.  Engineering items are listed as Bind on Pickup.  But World of Raids refers to them as BoE.   If they are BoP, it will suck big time and might push me over to doing BS/Engineering.  Reminds me a little of college.
