Set to Blow...
P.S. I am a 47, near 48, Warrior with 45+ gear and weapons.
Did it on my ele at 47.
Dont know what to tell you really besides try and keep your distance. Warriors can use bows right? Try that. Also you can lure her up to the ramp near the entrance to the cave system, so if/when you die, you can (hopefully) get back to her before she fully resets.
also make sure to stay far away from the destroyer crabs. I have no clue what is up with those dudes, but their tiny TINY mandibles have a range/hitbox longer than the crab itself…
When I did this I did die a lot but then I discovered that I can lure the mobs one by 1 if I do it properly. that way i only needed to deal with 1, 2, or 3 at a time. Also if possible try to revive some of the NPCs that are out of the Argo range of the enemies. They can be very helpful dealing with the enemies you separated from the group. Once you killed enough try to revive a few of the NPC Allies and start focusing fire on the Queen. The NPCs will serve as nice temporary tanks and the NPCs with their own names are the strong one you must have fighting with you since their special attacks are very handy.
I was finally able to complete it with assistance from a level 71. But even he said he couldn’t solo it at his level.
