I think its clear for any of you min/max RPG vets and D&D vets. Once you know what you're doing its really pathetically easy. Most of the goblin camp dies to a single hit, and thats before we have any huge AOEs.
Stuff needs more HP, more enemy healers, more challenge.
goblins should be this much weak, its theyr job. I'd say tier 1 enemies in general (1-4 PC lvl) are supposed to not pose that much of challange. Higher tiers and theyr higher CR monster are the real deal
A rogue practically one shot the 50 health boss with one sneak attack. Individual goblins might be that weak, but to make the encounter more difficult you'd have a lot more of them or some worgs/trolls joining in.
