I think this is the best all-round (offense, defense, clearing, single target) build I've played.

For non end game fights, I have Increased AOE/Firestorm/Glacial Cascade/Frost Wall for Concentrated Effect depending on my mood. Frost Wall is pretty handy in Heists and running through a narrow door into a pack is the only thing that can really kill me. Alas, just be patient and load up a bunch of VDs and wait for it to clear the other side of the door before continuing.

You can honestly use any Chest you want. Best is an explody+crit chance chest but that is very expensive even for a non-5L. Remember Skin of the Loyal implicit options also include +2 AOE which is better than my +1/Increased Damage chest.

Also POB suggests that Blade Blast variant of this setup is about double the dps but I'm not sure if real or not.
