Ok basically around Firelands I came into some gold (rare pet from the Exotic Satchel) and powerleveled BS so I could have the two "best" professions for a Prot Warrior, BS and JC (was Mining/JC originally). It's worked great for me now, except I have no way to get the materials I need for JC - in Dragon Soul this doesn't matter since they have the gem clusters, but I'm kind of worried going into Mists because I won't have any way to get ore to use and I just know that some douchebags are going to corner the market and charge insane amounts of gold for all of the ore and gems (and gold is always hard for me to come by), especially if beta is anything to go by (blue gems going for 5k+). I'm aware of the whole Harmony thing that you can buy ore with, but this would add yet another thing that I would have to spend a ton of time farming just to keep my professions viable (I'm more concerned about JC than BS at this point in time anyway since BS gear is less than heroic gear, no equal to raid gear like in Cata).
So basically I'm wondering if I should drop BS and pick up Mining again, and powerlevel it before MoP hits just so I can actually have a steady supply of ore coming in when I start MoP (and a way to make money too) without having to farm Harmony things just to stay viable. On the downside, I'd be giving up a really good crafting profession for a lackluster gathering profession, but I can't think of any other way with being fairly poor to fund my JC and BS endeavors short of lots of mindless grinding when I'll already have enough on my plate with leveling, gearing and getting faction rep (although I suppose I'll be collecting Harmony as I do all of those things), so I basically couldn't even really start on my professions until I got all of those things done.
