Your not showing in eq2u so its hard to now how you are geared. But given the opening solo quests provide upgrades in gear for even AoM raiders and the x2 even has an access quest series that takes you through a new heroic first, I doubt the x2 is intended to be first target in expansion for pugs.
But it is very doable and been killed by many. From our little grab in beta of whoever wants to come.. we wiped first try. So we adjusted to start with the adds and got them down ASAP and then took advantage of the small breaks in between the next spawn cycle to work on named. Once you have the add re-spawn starting again, repeat and bring them down immediately.
In the 59 seconds you had in that fight you should have been able to kill the first 4 adds, and be onto the each of the new spawns as they popped. If you left the adds up in that 59 seconds and just stayed on the named, I can see how nasty it would have been.
