I was curious on the current buffs from professions going into WoD. I currently have BS and JC, however I was thinking for DPS increase + CM's and proving grounds to changing JC to Engineering. I already have all the mats to change over, but I don't know if it's a good ideal going into WoD to change. I'm also I consider myself a solid raider so I was wanting to go with the best even though it may be minuscule going into WoD. Thanks for the reply's!
