I sent a bunch of time on my alts this week, and they've been leveling quite nicely without any pug issues. I did have a few issues on my Worgen druid. I was healing a run through Scholomance where the hunter was a bit trigger happy and/or ran into the next room and face-pulled some mobs. I managed to keep everyone alive, but just barely. The hunter did keep apologizing for the pulls and pulling aggro, but kept doing it anyway. About half-way through the drake room, the tank suddenly drops group. The hunter dropped a few seconds later. We got replacements rather quickly and continued on.
The new tank didn't know the dungeon, but we were able to guide her where to go easily enough. the rest of the run went smoothly until just before the final boss. In the room chock full of undead, the tank managed to pull the entire room and died before I could catch up on heals. I managed to get a battle-rez up and kept myself and the others healed though the resulting chaos.
Back on my shadow priest, I was able to score some cheap Cataclysm greens off the auction house. I have a set of the new level 80 cloth gear to replace my heirlooms when I hit 80, but these were level 79 greens that were above and beyond anything that came out in Wrath and filled out a few of the non-heirloom slots quite nicely. I also finally hit level 2 on my alt guild, and my main's guild just hit 25 this week as well! I don't know if there will be any raiding this week due to the holiday, but I will most likely spend some time on my main doing the new Troll dungeons.
