I didn't have much luck PUGing this in the Zalera server using Party Finder. So I transferred over to the Exodus server and within 24 hours of being in that server I found a group of folks in Party Finder and we downed Titan XM after only 2 attempts! A flawless (deathless) victory. Not bad for a bunch of folks who have never played before. We were not on vent or team speak. In fact, I was on the phone the entire fight talking to my friend.

Here's a video of the fight in its entirety (WHM POV, on the PS3):

So if you guys are having a hard time downing Titan XM I would recommend looking at other more populated servers. The Party Finder in Exodus, for example, is so busy sometimes that you'd have to scroll down to see the full list! Lots of people to play with and its much easier to setup groups/PUG things. Lots of highly skilled and well geared players. You'll even see t4 and t5 being listed in Party Finder.
