Did this tonight on the Mischief server. My 70 SK had like 13.2k-14.9k hps, and around 1k AC. I think I had closer to 15k at the start of the fight, but a couple gray-con adds added maybe halfway during the fight and I guess those mobs dispelled some buffs (including conviction). The SK has bazaar bought raid gear - almost all of it req lvl 65 (but most of it was near end-game in GoD expansion - weapon was only Cudgel of Venomous Hatred from PoP). No real lvl 70 gear to speak of other than Obsidian Cummerbund belt. SK did have 35% melee shielding and 84 avoidance.
The shaman was much better geared, with 2.0, Time's Antithesis, a few Demi plane items, etc. Though that wasn't really necessary, but the 2.0 clicky was handy and helpful.
I pre-buffed the shaman pet and the SK with panther and a HoT on both. I also clicked epic 2.0 on shaman then hailed with SK (starting the fight). First thing I did was use HT with SK to establish good aggro. I tried slowing immediately with Balance of Discord on the shaman but that resisted, so I then cast Malos. I then cast Malosini (from Pendant of) which landed the first time. I got a Balance to land "partially" after that, then Turgur's from TA landed. Poison dots from shaman never did land, but I did get Curse of Sisslak to land a time or two.
I mostly tried to keep Spiritual Serenity up on the SK, and that was probably all the healing that would have been needed. Shaman didn't have any issues with mana, and I did Canni AA once, but that wasn't really even necessary either.
Anyway, fairly easy fight. Clear the room first, just in case (Captain won't aggro till hailed so you can get as close to him as you want before that without aggro), get captain slowed (Malos, followed by Malosini or Malosinia will help), and keep 70 HoT up on SK and you should be fine.
