I think many of you need to read the OP's comments...he stated that his problem is the TURN ACCELERATION. This is not auto-aim, and I think it's just a problem with his wording in the blog. Turn acceleration is when you hold the right stick one way, and the longer you hold it the faster the camera begins to turn. I too think this is annoying, especially after playing CoD (which doesn't have turn acceleration) and really finding those controls superior to any other FPS. I think more people...
I think your logic in the last part of your post is flawed. Aim-assist does not have much of a factor in the decision to include a game in a gaming league. The best example of this is Halo 3. That has arguably the most aim-assist ever seen in an FPS, yet it's still the most popular game in MLG.
