Thanas for that. I find that really surprising. From very start I found per very easy...so much that I almost immediately went to highest difficult and have never put 1 pt in hp on either myself or ally.
I've also pvp a bit and find myself holding my own there even with this type of build.
One thing is that with a bit of hp/mp hit regen I find I can immediately regen what I lost.
Maybe 2 or 3 bosses have given me some trouble so far, and have killed me a dozen times before I got better of them, but not enough to make me lower difficulty.
