Delubrum Reginae Normal Trniity Seeker laser not scaling with # of players in instanc

World name: Sargatanas
Character name: Nacl Free
Monster name: Trinity Seeker
Class/Level: any/80
Party or solo: Solo
Area and coordinates: Delubrum Reginae Normal
Steps:
1. Engage Trinity Seeker
2. During phase change to yellow, when the stack laser mechanic happens, this will typically one-shot me if I'm the only one in the instance. It seems like this mechanic is not scaled to the number of people in the instance, or is doing a surprisingly high amount of damage compared to all of the other mechanics in this fight.

I've heard that stacking with Mikoto works, but I agree that it shouldn't be lethal if alone. Hopefully they'll fix it!
