I also like the fact that once you make a potion it will always be in your inventory and replenish itself when you rest, as opposed to the earlier games where you had to make them over and over to keep them available.
Damn I wondered why I couldn't make anymore... Thank you this has cleared up a mystery for me.
In battles I find pressing the 'Lock on target' key helps enormously (I've also popped this on my mouse using a thumb key, I also use another thumb key to cast signs) I changed the Tab button key which opens the signs panel to Q so it's a little nearer. I tend to use the roll command too as the new dodge skill is a little awkward to initiate.
As to what level I'm on I can't remember right now but I think it was the second...
