I'm running an Ice Crash Berserker, and focusing almost entirely on Grand Heists. The build is of course rage-based, which makes it poorer for bossing and their downtime.

I've integrated a lot of AoE radius nodes, and have it up to 39 units. I've got about 1 million DPS, and am wondering what tweaks or substantial changes I might have overlooked. The PoB (linked below) has some of the obvious changes integrated, such as maxing gem skills and qualities.

Several changes I'm considering and would appreciate input regarding:

1. On Ice Crash 6L: Swap lowest DPS Support (Faster Attacks) for AoE Support

   1. Lose Faster Attacks: 21% DPS

   2. Gain Increased AoE: +5 Radius, -2% DPS

   3. Or Gain Awakened AoE: +5 Radius, +16% DPS (1 Divine Orb)

   4. Either AoE support raises Ice Crash mana cost, would need catalysts or something else to bring it down a bit.

   5. Loss of chances to Freeze w/ fewer attacks.

2. As I level, I can free up 5 Nodes and get Serpent Stance normally, then pick up a different notable on anointment. Potential Notables listed below. Are there others that come to mind?

   1. Brinkmanship 20% Melee AoE Radius: +2 Radius

   2. Blast Radius 20% Dmg, 10% Aoe Radius: +1 Radius

   3. Fangs of Frost: 8% Dmg

3. I get Endurance Charges consistently as I'm always Leaping around, providing +14 elemental resists. I could drop 14 elemental resists on gear and re-allocate, but wouldn't be capped if charges weren't active. Is that considered OK?

4. What's up with Power Charges? I get Endurance Charges, are those Power? If so, why does my Crit go up when I get Endurance Charges? Blocking gives me a chance to gain Power Charges, but what kind do I get?

I know it's a lot of questions, but if you have input on any of them, I'd appreciate it.
