Easily my Lionheart Champion during BC. I first dropped 345 engineering and started from scratch with blacksmithing, though I had 375 mining. farmed allllllllll the way to 350 to make my Lionheart Blade under hellacious scrutiny for being a ret paladin, then farmed 12 primal nethers when they were BoP only and you could only get them at the end of a heroic. This was BEFORE they nerfed it down to only 8 primal nethers. Never did manage to get my hands on 5 Nether Vortexes for the Executioner...
