I always see a lot of people complaining about this mission. The only reason it's hard is because they have the quest Breaking the Broken (master) active. That quest will spawn the mobs at the start of Nightfallen Jahai. Just cancel the quest for now and Uncharted Territory will be a lot easier.
If you're to lazy to cancel the master quest... it's also possible to run.
