Guild Wars 2

Why should it be nerfed? They stated that not everyone will be able to beat the encounter. Only real issues I have are the camera and that there definitely is a difference in difficulty between classes (but I honestly don’t think that it is possible to design an encounter that is perfectly fair, where no class has a benefit).

To be honest I don’t really understand the problem. If you say you can’t take a break because you don’t want to miss out on the story progress, that is fine. But the story behind QJ consists basically (at least right now) out of one instanced event. If you do one or two balloon events you have pretty much experienced all the story. The Gauntlet is IMO only a little mini-game that has basically no effect on the story progress.
To sum it up: To complete the story you need at max an hour.
Doing all the achievements is of course a different matter.
