For the past few weeks, I've been doing solo rep runs of Molten Core. I decided to jot down the strategies I used for the bosses, and this eventually lead me back to this blog (which I've sadly abandoned for so long).
MC is actually pretty fun and fairly easy to do as a protection-specced paladin. Not only is it the only place to grind out Hydraxian Waterlords rep, but can you make quite a bit of money from Ragnaros alone (about 300 gold), find rare items that people will pay for on the AH, get a chance at not one but two legendaries in the game, and (for you tier collectors out there) finish your T1 set (and one piece of T2).
