Today's build has been sent in by a number of people now, so this week I'm taking a look at one of the more popular Arena Frost Mage builds -- 17/0/44. There are a number of variations of deep Frost builds, but this one goes far enough in the Arcane tree to grab the very useful and powerful Improved Counterspell. The Frost tree has been synonymous with survivability for a long time, so it's no wonder that it is so often seen in the Arena. As with other builds of this nature, it picks up talents that increase your damage output as well as those that boost your ability to stay alive. Frost allows you to kite your opponents, or hit them with reliable burst damage utilizing Shatter.
As usual, there is some wiggle room with the talent spread, so you may want to shift points around depending on your personal taste, or even the Arena bracket you spend most of your time in.
