I'd have to agree with xant (his original point at least), a good 1h shielder is more dangerous than a 2h. 2hs have more likely been softened up by ranged and missed blocks and then there's the shear effort involved in killing someone who has a much easier effort blocking. In battle, I'm more likely to die to a good 1h shielder, than a 2h. Not counting big mob battles, there the balance lies in favour of the 2h. And on the duel server I also prefer the 2h.
