I can say right now, with 100% confidence, that the Kniles the Flenser fight is extremely overpowered and nearly, if not completely unbeatable.
Kniles himself will battering ram at least 2 of your party into knockdown and proceed to either full party stun with Electric Discharge or one shot any non-tank characters with low or no armor.
The Meat Golems will two shot anything, including your tank, by hitting disease on them and hitting them for nearly 35-50 damage.
And the worst offender of the fight, Kniles will trade places with a Silent Monk and that monk will probably become damaged right away if not at some point in that fight and that will aggro every monk in the dungeon, now even though there is only 3 in that area with Kniles it really doesn't matter at that point because you WILL lose. The monks are overpowered if you have to fight more than one at a time, Kniles is...I hate his tactics but I have to say it makes sense with the new AI and is "balanced" in a sense that he knows how to use his environment, but the monks need to be made to not go aggro if enemies damage them or/and they HAVE to not be able to all go aggro if one is damaged. The golems and kniles will be manageable only if the monks are changed or if a player overlevels and overgears, comes back and nukes Kniles, otherwise they won't have much hope fighting him as the primary escape plan. I had to take the boat out as challenging Kniles was just not an option.
