Hey guys,
I am not sure how many of you attempted this place. If you have that's great, it really isn't all that bad with the exception of some bosses. Anyway from my analysis, I concluded that shadow priest can at most solo 11 out of the 15 bosses available in this place. The ones that priests cannot solo are Thaddius, Instructor Razuvious, and of course Patchwerk. Apparently Gluth is possible with a high ilvl.
Anyway I just have just completed (as of yesterday) all 11 of the 15 of the possible bosses.

For now I guess Naxx is done for me. You are also welcome to see my other solo videos.
Btw, just in case you are wondering, Kel'Thuzad and Gluth are equal first in difficulty. They both took a similar number of attempts and they both posed a similar challenge, BURN THE BOSS! Although in perspective Kel'Thuzad is probably slightly easier since I downed it at a lower ilvl. Another boss fight that involves a DPS check is Thaddius, and that boss required higher ilvls than the other bosses.
