On my 80 DK i ride around the western half of Wintergrasp, while the games Not going on, and can usually farm up a stack of 20 titanium ore in about an hour. I just hit all the saronite nodes i find and usually end up with quite a few stacks of saronite once i'm done. Not to mention all the eternal shards and gems as an added bonus. Usually theres no one else farming when i'm in there, every now and then i run into someone else farming and i just skip by them. Ganking/pvp is minimal on the server i play on if its in between games. I find myself running out of eternal fires more than titanium, theres a nice area full of fire elementals to the far east of the zone and the Elites(visible only when your faction controls the zone) usually drop 1-3 fire shards per kill, and there pretty easy to solo.
