Redfang is such a pain in the ass. Blunt weapons do more dmg to him then normal other weapons. Pull redfang down to the bottom of the spiral. Find a spot to pin him, and make sure he doesnt face the raid, cause of the silence. Have a kite team to kite the adds during the whole event, have them run up spiral and then jump off, and keep doing that. Redfang has a single target ramp. DPS redfang as much as you can, the faster you do the event the easier it is. Now when redfang depops, I believe he is only up for 2 minutes at a time, could be 3 dont remember. Have everyone gather very tight with each other. When all the adds spawn have Druids cast their AE root, Wizards cast AE nuke, and Enchanters AE mez (word of morell and echoing madness). The adds get hurt/die when a nuke hits them when they are rooted. Rinse and Repeat
