I got into Zul'Aman for the first time last night, with Origin as my host. Long story short: 5 boss wipes, 1 boss kill.
Frankly, we didn't have the DPS, the heals, the know-how, or the organization to tackle ZA. Several of us had never been there, and several were also undergeared. (Some, significantly.) We had heart, though, so we tried. And tried again. And again.
But it wasn't enough.
We did manage to down Nalorakk, the Bear, on our third attempt.
In the end, it was a long night and we walked away thoroughly beaten. But I did get to learn a few things and get a feel for the place, so it wasn't a total waste.
And yes, I am still walking around with my name and title visible to me. Give me a few days — I'm sure it will wear off eventually.
