1. This build is not good for end game elites, but for leveling up it's OK.
2. Mage role is crowd control and damage dealers
3. Healing causes aggro on the mage, it's OK for leveling up at the beginning not for elite maps A dead mage is not good for the party.
4. Healing + Shield will slow down runs, you are wasting a damage spell for healing
5. Ya need root on your clock build.

Interesting though, it's smart to try different things with your class that is for sure. Just be clear that this isn't for elite maps~~
