What skills should I use for Mage?
I kinda want gale force, but I'm not sure.

I want the build that most people use. Here is what I think

Gale Force
Lightning Strike
FireBall
Time Shift

Is that good? Lots of people in forums are not using gale force. And I don't get the point of lightning strike, and I felt like frost bolt was pretty useless, so I'm not planning to use it, but if it's good pls tell me. Also lots say arcane shield is good, explain please.
