Again, since you've only played the demo, you really haven't gotten far enough to know how bad the new skill system is. Don't get me wrong, overall I still like the game and will play it (although I'm quitting until there's a patch to address some of the buggage). You can think ahead all you want about what skill you want to use, but until you know every single piece of equipment in the game, you're merely guessing as to what may be available once you get to X level.
