These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Anticlimax Boss: Quite a few. Most of the named quest mobs can be soloed easily and the solo instance quests group the player with NPCs so monstrously powerful that they would be able to finish the quest on their own if their AI was a bit more competent. Thulsa is the biggest example. Despite being the main antagonist of the story his divine form only has standard crab BAM melee attacks. His right hand woman Akasha and later ally Killian at least have unique wipe moves.
