This left me very depressed on two fronts. First the negative attitude from the experienced players. It stated at the beginning of the run that a member of the party was doing this for the first time. Second, I'm a little dissapointed in a mission design that pretty much expects you to have to research the fight before you attempt it.

Thankfully, after doing some research, I attempted it again the following day. This time the groups Tank was new but the Healer was patient in explaining the fights mechanics to us and was supportive while we messed up a couple of times.

I'm left a little ambiguous about going forward though. There's a lot to love about this game but I'm concerned if this is the dungeon design going forward. If the difficulty is through instant death mechanics because of ignorance I'm not sure I want to perservere with that. Failing due to bad teamwork or tactics is one thing but cheap instant deaths like that suck...
