It doesn't matter how much tenacity or dh you have. The stat vslued don't magically change when you hit 1500 or some other number. Tenacity doesn't suck when melded but rock through gear. So much nonsense spead like rumors through these and other forums. If you think dh is better, focus all your gear and melds on that. If you think ten is better focus all your gear and melds on that instead. Tenacity seems clearly better to me but some would rather do 2% more dps and take 10% more damage.
