I can’t believe the complete apathy on ArenaNet’s part with this. I paid good money for a Deluxe Edition pre-order on this game and I’m stuck at this junction of my main storyline quest and to my knowledge, MANY people have been complaining about this from the very start and ArenaNet has not even responded to the effect that they are at least trying to resolve this issue. As for keeping Traehern alive through the quest, that is just stupid and nearly impossible for all but the most skilled players at or about Level 60.
Although the game should not be too easy, it should at least be able to be accomplished with reasonable expectations for all who buy it and staying alive yourself is hard enough at that level but having to babysit a careless NPC at the same time, just amounts to a broken game and poor design on the developers part.
