In Timberline Falls there is a Skritt colony named Fionnghuala Scratch. A nearby heart has you help the colony against Jottun invaders. Even though you’re helping the Skritt survive, they all attack you on sight except for the chieftain and NPC that grants you the quest. You’re clearly helping the Skritt and I think this is a bug.
Also, someone already reported this 9 months ago. I’m suprised it hasn’t been fixed yet. https://forum-en.gw2archive.eu/forum/support/bugs/Help-Fionnghuala-Scratch-bug-skritt-all-hostile
This game is not about out-DPSing you. It’s about
out-flashing you.
