Ah, sort of a specialists item. Well, I´ll keep it in my inventory and maybe try it again later...
On another note, reading through this thread and another one that was linked here helped me get a little better. Most important thing is to be aggressive as a shielder and I was pretty passive
Also, I noticed that if you wanna play good first person is just out of the question in this game. It´s a shame, though, I much prefer it.
Oh, and I now use the plate covered round shield. It serves me good so far.
