DK usuage for Chimaeron

[Dorian]

So up until the point last night where my brain checked out and I stood in so much fire...repeatedly, I found some interesting things during the Chimaeron fight. Since it seems that the fight isn't a dps check until the very end would it be logical to run a blood spec but in dps gear. The reason I ask this is because with deathstrike I can essentially keep myself up as long as I make sure to have the runes up as the boss is finishing massacre. The main thing I'm thinking about is using rune tap to save the healers a little bit of grief. It heals me for 10% Max which puts me over the 10k mark and hits everyone in my party for 5% of their max health. With will of the necropolis whenever I get knocked below 30% the rune tap cooldown refreshes and is for free. Rune Tap itself has a 30 second cooldown and will of the necropolis has a 45 second cooldown. Granted in 10 mans it's not so important but in 25 it could be useful just to have me in the tanks group so that after massacre they get an immediate 5% life heal, since I'll be doing it to keep myself alive anyways. Not sure how useful it would be but it's a thought.
