This boss fight was really well done. I completed it solo on the first try with my power/toughness/vitality warrior with a rifle and greatsword. We need more bossfights like these good job Anet. My only point of qritique is that this achievment is a bit too easy for someting called challenge mode. Something like challengde mode tier 2 would be nice with more crazy boss mechanics. Just to get me busy for another couple of days or weeks, to give you that special liadri/clocktower feeling.
The achievment wasn’t that easy but completing it on the first try is not something i would want for the hardest content of this patch.
But nevertheless keep up the good work Anet
