Yeah Saurfang is the 4th boss in ICC. I don't know that I'd recommend what we did, I will explain:
Saurfang periodically spawns 2 bloodbeasts (5 in 25 man). They will increase his energy every time they hit someone, which is really, really bad. We did this 10 man. Our tactic was to kite them to prevent them from hitting anyone.
Most of the raid sat on top of Saurfang. I stood off to the left and a hunter stood off to his right. We each took one bloodbeast each time they spawned. I (as arcane) hit it with slow and then would hit and run until it died. A DK would come out (chains of ice) and help us if we were having trouble. There was usually only time for one or two shots at the boss in between spawns. We 2 healed it, so that really left 5 DPS (minus the DK occasionally) on Saurfang. It was a bit rough.
While this did work, it was not efficient.
Next time (probably tomorrow night), I'm going to try using a full permafrost (60%70% slow) Blizzard to grab both bloodbeasts myself. If I need help downing them, I hope to keep them near the boss so we can try to AoE them down without losing too much DPS on Saurfang. I think this strategy also scales better to 25 man, but we're not to Saurfang yet there. The ~1k DPS hit that I take should more than be made up for by allowing 1 additional DPS on the boss full time (or getting a third healer, or something).
This is really my first time on "progression" raiding, having come in when things were on farm before. I'm sure it's old news to the pros here, but I think having that fully specced Blizzard is helpful even on the harder trash pulls in ICC.
edit: 100 posts, yay!
