Pr.Crystal has been double dipping in recount and skada. Even more it is too bad talent for high mobility raid bosses.
Solution: Mage goes in unstoppable presence. His single target spells now deals AoE dmg 8 yards radius and his AoE spells now deals double damage evenly split among all targets. Spell dmg increase by 10% for Frost and 30% for fire and arcane. Cooldown reduced to 1min down from 1.5min.
PS:So you can use it with frozen orb. If it is overpowered cooldowns of both spells can go to 1:15.
Comet Storm cooldown decreased to 15 sec down from 30. Now grants charge of fingers of frost.
Meteor strike cooldown reduced to 20 seconts down from 45. Now grants a hot streak buff.
PS: Arcane orb grants arcane charges per target hit. It is way better than comet or meteor so they need a buff to make them appealing.
