There's a bug? Hmm.. that sucks. They even made a point that you can change difficulty on the fly (eg during battles) so that you can.. you know, choose the one that "best suits you".

Sneak is essential to my playstyle. I can take on some bandits in close combat, but that's about it. Saber-cats prolly need potions (been a while since I fought one square). I won't even think about direct combat with bears, trolls or giants.
You can't block with dual-wielding, but you can sure as hell:
-Pummel them with alternating attacks that drain their stamina like crazy - then stagger at the end
-Use lots of dual-power attacks (or even normal power attacks for the +25% critical) with my good stamina to take them down fast
-Use dual normal attack to give 14 x 2 x 1.4 (one-hand bonus perk) x 1.15 (ring bonus) x 15 (Assassin's blade) = 676.2pts dmg on first strike.
Halve that if you want cool animation on weaker dudes.
