I'm not a fan of gearing up. I hate watching my gear fade into obsolescence. I hate swapping out my legendary Fangs of the Father for a set of blue weapons that were given to me after I washed a few yaks and played the role of a pre-employment drug screener for some amped-up goats.
Bill Gates infamously picks lazy people to do difficult jobs, because they'll find the easiest way to do it. I am that lazy person. I am always looking for the quickest way to get my rogue into raid-ready shape. The quicker that my rogue is geared up, the quicker I can get back to Eviscerating leveling players of the opposing faction. With a couple of weeks of grinding daily quests and some heroic dungeons mixed in, your rogue can be ready for the first tier of MoP raiding.
