Just did Thornmarch Hard (because im stupid and forgot that i needed it for the main story line) and our party wiped after our first try due to a mixture of first timers and the chaos of a proper add kill order.

Even with the echo buff we started to wipe on the second attempt but mixed with a bard LB3, we got back up, killed the last add then downed the king. Then we all went on our merry way (someone even go the whiskers).

Glad i didnt have to spend too much time praying to rng that I got an overgeared group who was doing it just for fun. Even with the buff we still had to pay attention to the mechanics.
