I'm reading the other class previews because you have to know your enemy.
Mages get ...
"Wall of Fog (level 85): Creates a line of frost in front of the mage, 30 yards from end to end. Enemies who cross the line are snared and take damage. The mana cost will be designed to make Wall of Fog efficient against groups, not individuals. This spell is intended to give mages a way to help control the battlefield, whether the mage is damaging incoming enemies (Blizzard can be channeled on top of Wall of Fog) or protecting a flag in a Battleground. 10-second duration. 30-second cooldown. "
Majorly OP, if that doesn't get nerfed I will be ABSOLUTELY AMAZED.
30-second cooldown? rofl
