I've had an undecided opinion on the personal story quest. I thought it was all a little cheesy, it was too easy in my opinion and the story made no sense half the time. And of course, Zhaitan, the main "boss" did a Deathwing all the way through the story. We saw him once. When we killed him. And it reminded me so much of Dragon Soul, right down to the fact that in the last dungeon, Arah, we jumped on gunships and did a couple of bosses before killing Zhaitan for good. This was a terrible instance, and I really expected ArenaNet to come up with something better. We had absolutely zero combat with Zhaitan, in fact, he gets shot by a laser cannon in a cutscene twice and then we finish him off while he's cowering like a little girl with cannons on a gunship. To say that it was a disappointment is an understatement.
