So I did my first 8 man content (the boss fight) and man what a clusterfuck. I have no idea what happened, probably got hit by every single AoE and attack there was, yet my health never went below half and the fight was over in a second. So I have no idea if the fight even had interesting mechanics or not.
A little disappointing if I'm being honest.
Cape westwind doesn't have any real mechanic, the only new thing is the off tank picks up ads. The 8 player missions are really messy the first times, only after a while do you get the general flow of the combats.
