I just beat him this morning, and it was less difficult then was portayed in the forums. I think that most people who find this unbeatable just rush through the story. I think some of the sidequests were harder and overwhelming. However, he is not easy and a bit annoying. If you are a mmo player, i can understand that you think it needs a nerf. But if you are a shooter fan ... i think differently of you :P
btw: Blur is really good to get out of those situations where he comes up to you and wants to slash you with his sword. Also, dont fall for the melee damage option in blur ... horrible noobish death awaits you lol
