You can regularly solo this quest with ranged magical cantrips or a bow without taking a single hit. None of the enemies will outpace you, so long as you are smart about where you run and don't end up backed into a corner(Even with the dead ends, you should have adequate time to kill the enemies since they move so slowly). This quest is dangerous for melee combatants, as the things that do hit you, will hit you hard and the boss has an extra devastating trick for things it catches. I think this design choice was intended.
That said, I think the quest itself only has...2? Actual loot containers. I guess the loot could be increased, but I think 1-2 loot containers is the par for 1-6 quests anyways.
I'm also in favor of removing the boss's nasty trick so melee inclined people can have a whack at it so to speak, but that's just me.
