If you roll 87 and make a berzeker, then your party will play like diablo right out of the keep. Mages can be kinda cool if you can overlook that theres almost no difference between a single one of them, except edwin.
I already told you to stop talking when you're only embarrassing yourself. Oh wait, you added all those weasel words in there, I guess that makes it fine.
The problem is that the maps are far too large and open. Unless you are staring at a guide with names on it, 90% of the time is spent going back and forth in rows and columns like you're mowing the lawn searching for something that isn't a gibberling pack... Not wanting to spend the majority of your time walking around aimlessly in circles killing trash mobs isn't ADHD, it's called not being retarded.
No, you're exaggerating to a comical extent and just proving that you want an on the rails, cinematic experience with hand holding:
Maybe this picture from another genre will help you understand. BG1 is on the left and has some actual exploration. Now I'm not saying that BG2 is on the right, itäs not, as there's still some exploration left aside and some of the maps even have a few, minimal, empty spots, but bye and large Bioware designed BG2 maps so that
A) you cannot get lost
B) you cannot miss anything
C) you constantly encounter something
Are you seriously claiming that RPGs get better if you remove exploration? Because it seems to me that you are. Which is why I called it the "ADHD" experience. You used Underdark as one example and it's a great map where you literally stumble into an encounter every other step - every corner and room of the map has an eouncter of some kind, not counting the random ons. You know what I was expecting to encounter in the Underdark? The actual Underdark: miles and miles of corridors with few but dangerous monsters - something like the mines from BG1 but on steroids.
