I first deliberately selected Maraudon Purple. My action bar and macros need improvement as I'm positive I wasn't taking full advantage of the optimal rotation. A warrior DPS kept playing "Off Tank" and pulled or played threat games. It wasn't much fun, but I needed to concentrate on my own duties and let him play his own games. The run was fast, but confusing and nothing fun dropped. I did ding level 41.
I spent a bit of time rewriting macros and redoing the action bars. I had hopes it would be an improvement. This time I allowed RND to determine my dungeon, even if it meant orange or Zul'farak. Instead it returned me to Maraudon Purple. I knew better where to go, but this time I had an overeager and overpowered Rogue that wanted to lead. Things were still confusing although I was doing much better DPS. I wasn't doing any better at managing threat and lost one DPS when he pulled something away from me and I didn't notice until getting ready for the next pull and saw he was dead. The healer was just starting to rez him when I got to him. The rogue was heading on by himself, but survived his solo pull.
In our eagerness, we had passed the boss and needed to backtrack. As an encounter, it went the smoothest since I didn't need to worry much about AoE threat issues. Nothing dropped for me and even the blue bag was a Tumultuous Ring that didn't match my needs.
