After figuring out that 7x70=490 and I was done with Heroic Valor Point bonuses for this week, I decided I'd read up on and try out the new Zul'Aman randoms. Got sucked into ZG with two bosses already down. Not sure what happened to the last DPS, but I do know I'm always glad when I hit an instance that's nearly done. Seems to happen most in Grim Batol.
Anyhow, this Zul'Gurub Heroic Guide on Icy Veins is quite good. I really didn't know what the heck I was doing, caused at least two wipes, and offered to drop seconds before I saw the finished dungeon plaque appear. Still got to roll on drops, which was nice. I guess I did okay, but boy, I had some learning to do.
Having gone through three bosses now, though, combined with the guide, I think I'm good on at least two.
