Nice find and thanks for sharing.
I can definitely see a point where I would reach the road blocks the author of that article points out. I also can understand why the leveling system can be harsh at certain points.
Still, for now at least, I'm not high enough in level to hit any of the roadblocks or other points of frustration he's point out. Let's see how I feel after playing for another week or so. I'm still having fun with this game at about 40+ hours into it.
