If they *DO* add options in the ruleset system and stuff like that on release... wow. I will cry actual tears of joy, no joke.
I wouldn't hold out too much hope for that, given that even the level design centered around maximizing barrelmancy/surface effects.
Zhentarim hideout with it's leaking barrels of oil strewn about, with burning torches feet away from causing utter oblivion, is about as moronically DOS as it gets.
This place makes sense when it comes to the amount of barrels and other explosives. When we get there, they prepare to blow up the entire cave to obliterate the evidence of their presence.
The even bigger problem with that place is that...
...you can initiate combat on high ground by pushing/thunderwaving the boss and her lackeys down, destroy the ladders and wipe out everyone with ranged weapons without ever being at any kind of risk against superior numbers because of the advantage/disadvantage swing. They will all just obediently stand down there waiting to die.
