Did something I haven't done in a while last night...left an expert roulette right after the first boss of Stigmascape.
Tank was pulling one group, then when they were at around 1/3 health would run to the next group. I was on RPR, other DPS was a BLM. The tank also would turn the boss so that the rear was always in the fire puddles. Decided to just drop after that and go do something else for a bit. Definitely felt like it was going to end up being a very long run that way(things were also dying quite slowly...)
