Couple of interesting articles in relation to the post from Blizzard about stat changes in Cataclysm.
Both of these articles offer quite a deep insight into how the potential changes might play out for Shamans. The increased stamina will be welcome for enhancement shamans. The weapon skill change is a subtle one. As soon as you learn a weapon you are instantly at maximum value for that weapon. No more wild swings on mobs trying to train yourself up. Is this a boon, or is it another step along the line of dumbing down the game?
