Every time I attempt dual wield weapons it doesn't go very well. I find it impossible to defend myself, especially when there is no way of lessening the blow of an incoming power attack.
The extra damage output you can get from dual wielding weapons just doesn't seem worth the extra vulnerability to me, although I don't know if this is because of my play style.
So I guess what I am asking is, is there a way to make dual-wielding an effective strategy for the core combat spec of a character? Or is it merely something that's a fun little add on to play around with every now and again?
