Dual boxing ICC- Shadowmorne quests

[Mickthathick]

I have recently resubbed 2 accounts for WoW just for mucking around and tyeing up some loose ends (god what is wrong with me, I'd escaped for 4 months!). One of these loose ends is finishing the damn Shadowmorne questline on my pally (and maybe even starting it on a dk).

I need to complete the Blood Queen absorb, the Sindy absorb and then get the shards and I'm good to go.

How easy would this be to achieve dual boxing with a pally (tank) and a frost DK? I only ever tanked in ICC and I have no idea how the whole biting thing works for the Blood Queen. The Sindy absorb sounds trivial (I just can't kill the boss too quickly).

I've read similar posts on these forums and it sounds like I should be able to heal the dragon (Valerinya?) if I switch the pally to holy. I was thinking 10m to begin with, then switching to 25m when it's time to collect the shards (maybe even 25m heroic).

Any advice would be much appreciated!
