One thing I noticed: I see a lot of top notch posters attaching sims and other results to their posts to prove their findings. I think it doesn't make a difference if you can't post for 1, 2, or 3 days regardless of gear.
One thing I noticed: I see a lot of top notch hunters with very low haste values. I think it doesn't make a big difference if you have 600, 800, 1200 or 1700 haste rating with high end gear. Stats are very well balanced as it seems.
