I want to just say that BW are as usual major trolls in the challenge department and I am pretty sure that someone somewhere at their offices is laughing pretty hard right now.
The undying challenge is let's say... frustrating to complete with pugs.

Omg, I tried so hard to keep them alive. And I was not even playing perilous, it was merely threatening. I tried using Keeper and barrier everyone. But there was always that lone archer which somehow got away from the group and in the exactly 3 seconds that he didn't have barrier died right away. On wave 5. After killing the RTC. With two enemies left on the map. Wuuuuuuut.
Then, in the lobby I jokingly tell the guy that we're trying to do the Undying challenge and to please please not die. Which is something, since I never ever speak on mic but it was an important occasion.
Of course, he dies. And he's level 20. On threatening. With barrier to go around almost always. A disturbing amount of facepalms were had.
Then, I decided that the best defense is offense. Just grab Izzy and kill everything before they manage to get to the pugs. Good strategy, except it doesn't work for wave 5. There you just cannot kill everything before the pugs manage to get themselves killed.
So, I tried the Virtuoso. As a matter of fact, I rarely play him and Izzy on threatening (just to level up from 1) since they are so powerful. Infinite barrier, amiright? What could go wrong? So we do one match, and indeed, by infinite spamming barrier and power chord everyone is alive and well. So, let's continue with him. Second match, wave 4, Tevinter ruins. At the last area with the rogue door on the left I, a lego and keeper fight the enemies because we got the aggro and otherwise they would have followed us into the room. However, a wild assassin appears! They use open the treasure room while everyone is fighting a group of enemies! It's super effective! Assassin dies shamefully (while I curse at everyone from their family three generations back, on mute of course. This isn't Call of Booty). How did they manage to do so, I cannot even fathom... there wasn't a revenant in the room, just some warriors and archers.
So... yes, I needed to vent that. I hate all the pugs that I played with today. I cannot describe how much I hate them. #firstworldproblems
