100% agreed on Mountain Fire. It feels up there with like, the Tank LB3 in A12 in terms of "cool stuff" for tanks to do. The pacing of the fight is really great, I think my only complaint is trying to figure out PCT uptime during the sequential party stacks at ~4 min, the movement feels just slightly too tight to fit in any of my casts and the puddles are too big to stay inside of my circle, so I have to delay until after that
