I am on the team that believe the fight is currently fair.
I could beat it at the third try without cheese(lvl4). Been honest there were like 2-3 combats that was challenge enough to make me open the inventore and: "-Shit, I am on trouble, what can I do to turn the tides of battle in my favor?"
That for me, personally, is pretty important. It feels like the itens that u got matter, like the decisions to help or kill someone that eventually reward you matters, that the potions and itens that you bought matters.
I am really not looking for a walk in the park (not judging who does).
Finally, I think they are currently testing different difficulties simultaneosly. So don't really bother that some fights are to hard for you, or to easy. If am right about this, the fights that u are thinking to "off" will be adapted to the difficult you choose.
