I realize I don't raid anymore, so feel free to take my sentiments with a grain of salt. However, if I were to start raiding again, I would want to raid with this guild (I'm assuming that you'd have me!) because I like the guild's raiding atmosphere and the guild's leadership.
Therefore, for what its worth, I would happily follow ATR off of Skullcrusher (depending on the intended server and not doing anything crazy like going Alliance).
Also, I came to Skullcrusher toward the end of Tier 10.
Maybe it's nostalgia, but Skullcrusher seemed quite different then and in comparison, Skullcrusher now seems moribund, lethargic, and more to the point, dying.
