This may sound unfriendly, but as a first comment I would say it’s better if people leave out their life stories out of these posts. I like reading other peoples views here on this forum but for some reason people are writing short novels about their background and personal life to give their arguments extra weight. It makes it hard to distill the main messages of substance in my view.
I agree that the surface, special items, items thrown etc are a bit overdone now. Would be nice if they can dial this down a bit. That being said, I feel overall that the game is super faithful to the DND rules, almost to a fault I would say.
The rules from the pen and paper setting can and should not be directly translated into a computer game, they are simply not made for that purpose so slight adjustments in my view are fine. I also believe Larian should give their own spin on this setting and these mechanics.
Then on the difficult enemies, it sounds like you ended up in the hardest area of the game early on. I personally like that you are punished if you end up in a higher level area. You can always teleport out if you’re stuck.
Overall I do not disagree with your points per se but it basically boils down to balance issues. Toning down use of items and special surfaces in combat and managing difficulty of encounters. Seems to be exactly the purpose of the EA to work on this.
Then finally your comment “start over” doesn’t seem very productive. They seem to be very far into production so starting over does not seem like a good plan.
