Oh hivemind, I call upon thee!

So, ever since the announcement I've been glancing towards the Battlemage and Fanaticism nodes of the Inquisitor tree and decided to try and conjure up a quick idea for a build using those two.

While perhaps a little unconventional, I decided to go for Frostbolt and Ice Nova, coupling it with a Debeon's Dirge. This bad boy adds roughly 300 to 500 (cold) damage to your spells when using Battlemage.

The general playstyle would be just running around Cyclone-ing and shooting Frostbolts via Cast While Channeling. Every couple of seconds you'd stop and pop an Enduring Cry (for extra defenses and the buff from your weapon). When you reach a harder mob or pack, you can stop and self-cast you Ice Nova with the Fanaticism buff that will be pretty much always up due to your Cyclone.

To simulate the new Ascendancy nodes I made a couple custom flasks - it might not be 100% correct, but I believe it's pretty close.

Without further ado, here's the PoB (using the community fork btw):

There are a couple of things that I'm sure could be done better, or at least improved at and that's where I'm counting on you guys and gals!

1. The damage numbers seem fairly weak. If you have recommendations on what could easily be improved, please let me know!
2. Defenses! Due to lack of a better idea I just went for Mind Over Matter (and Arcane Cloak). Coupled with Enduring Cry and Immortal Call on CWDT, it should be decently tanky.

One last thing - suggestions that keep the build league-start-able are preferred!
