I concur, i'm definitely in for this. I actually read on teh official foram that a team of THREE lvl95+'s can do Valley of Oblivion with very little trouble. It's supposedly easier than Marksburg.
If that's the case, then all of our 10x's and 9x's together can definitely clear Marksburg with enough time to slap Pho afterwards.
I'm in your timezone so whatever time you pick is good, just don't pick a weekday.
