Yeah, I had to turn it down from Blood and Broken Bones to get a feel for the combat. I was trying to over-rely on block I think, and not managing my signs very well. Going a lot smoother now and I'd probably turn the difficulty back up again but... I think I've screwed my build a bit. It might have to wait until I can respec (which I hear is possible at some point).
Also... I did notice I'd played for over seven hours (which surprised me!) and yet I'm only level three and only just about to leave the starting area. This game is going to keep me busy over Christmas!
I gave up trying to use "block", as I found it very hit and miss.
You can at some point buy a potion that will enable you to re-spec your build.
