You should be able to block with the 1H Weapon like in Oblivion, when you didn't have a shield you just block with your sword, plus you have to block each time an enemy strikes to block the attack not just hold down block which seems awesome (to me) and may lead to counter strikes. :mohawk:
If you can't block with a 1h weapon, I will not buy the game, and I will tell everybody I know not to buy the game.
It would be utter crap to not be able to block. I understand much less effective blocking, faster weapon breakage, random weapon breakage, active blocking, or just the inability to block missile attacks, but I absolutely will never understand no blocking ability.
