Tbf, if it weren't for the EA exp cap, it wouldn't be nearly as hard, because you'd be deep into level 5 by the time you enter the Underdark (which is a huge power spike for all characters).
I suspect playing the same encounters on release will feel like night and day.
Oh yeah wanted to mention this but I forgot. Unless it will be drastically changed, I can certainly see how we could find ourselves reaching the underdark at level 5 or even 6 in the full game
