Torchlight 2 Berserker Build Dual Wield

So, this is a edited version of a post I made in response to a topic about builds I posted over on the Runic Beta forums. I put a lot of effort into it and thought maybe people over here would also find it interesting, it's not likely to get a lot of notice where I posted it.
I rebuilt my berserker around items I'd found with my first berserker (yes I've played two berserkers to level 21 during the last 10 days). I'd been hearing that ice element based berserkers were terrible, but I realized that the itemization was there to make them incredible. I kept running bosses and finding stuff, then slowly formed a theory of ultimate ice berserker. So was born the Ice Queen.

Theory: Massive ice damage bonus, massive critical damage bonus, high crit rate (to get into frenzy quickly) and massive HP for healing (because all the zerker heal skills heal for a percentage of max) would net an unstoppable berserker with insane damage because all those percent increases multiply each other. In other words, my ice damage is more than doubled. My crits then triple that number. Et cetera and so on with other additional damage bonuses. Synergy!

Equipment and bonuses: Rather than type this out, I'm screenshotting and cropping, enjoy an imgur album. I skipped most of my Badlands set because there's nothing noteworthy there except the set bonuses, which you can see on the items I did screencap. - Photo Album - Imgur
Stats: My stats are fairly rounded. I basically figured out what I needed for the items beforehand, realized I couldn't make it all in a level 21 character, and found an attribute enchanter to waste a lot of money making it possible and giving myself some obscenely high attribute numbers. My actual natural distribution is 1 point in Focus (I had a lot of Focus on items and didn't need that much, but I needed that one point in order to get something equipped early while leveling!), 49 Strength, 32 Vitality, and the rest dumped in Dex to improve my crit chance. Also if I find better weapons, I want to be sure I have the stats for them. Basically the stat placement was mostly about getting items equipped.
Skills: My skill selection is almost entirely passives. I use 1 active attack skill, Shadow Burst, in which I placed only 1 point. I use it to break shields and as an OH SH-- last resort healing/escape, because it heals me for 6% of total every time you hit something with it, flings you forward even through enemies about ten feet, and makes you unhittable while doing so. It's also very fast, so as long as you have the mana you can fire it off back and forth through a pack taking no damage and healing. If you're in frenzy the crit heal passive also applies (it works with any damage dealt that crits) and will heal for another 9%. Here's my active choices in pictorial form with the all my stats pages as well: Photo Album - Imgur
The reason I have maxed out Blood Hunger and left Shadow Burst with just 1 point is because you don't want to waste time Shadow Bursting. It gives you no charge and does poor damage even when maxed out. It's a very slow way to kill things. My basic weapon swing crits do 10 times more damage than my Shadow Burst crits because of the ice damage synergy and the fact that maxed Shadow Burst is still only around 60% of weapon DPS. I'd rather soak 9% of my health per hit while obscenely defiling my opponents with massive crits than soak 17% via Shadow Burst crits for much less damage. I could have maxed both without giving up either Howl or Cold Steel, and those are both vital to damage output. Honestly I rarely need to use Shadow Burst, and when I do I'm making space rather than using it to heal. I shoot through the mobs, run while I pop a potion, hit Battle Recovery, Shadow Burst back in for a little more health, then go back to beating on them.
More theory/explanation: With over 2300 HP, 6% healing is about 132, and 9% is about 220, both together is 350-ish. One of my weapons also has a 3% life steal, being percent of damage dealt, which adds about 15-20 on a regular hit, and about 55-75 on a crit to my on-hit healing. My polearm has ridiculous reach and splash, my crits will usually kill whole packs in one swipe and net me extra healing. It works great with packs plus an Elite as well, since I can swing at the elite, hit everything around it and stick them in place. The hammer/shield combo nets me slightly less healing but more damage on single targets and superior defense. The shield has 29% block, and my vitality adds 11%, bringing me to 40% block rate. Either way I'm essentially unkillable by anything while my frenzy is up and I'm swinging away. Because of the high damage of my weapons and the skill that gives you longer frenzy, it takes me about 3-6 seconds (depending on luck with crits) to get from zero to full charge, and then I have 12 seconds of constant crits that heal me. This was actually a surprise, but it seems your charge amount is based on your damage relative to your level. So the more OP you get, the faster you fill your charge.
Tonight I killed the grand regent - the last boss available in the beta - on elite in just over a minute, no deaths, 1 healing potion used. I completely ignored his adds and just slapped him till he died. Don't get me wrong, I still had to Shadow Burst and pop my heal skill and a potion I had when my frenzy dropped, but that made me stop attacking the Regent for about 10 seconds, after which I was back on target with some extra damage reduction. It feels pretty good - the first time I tried him on Veteran with my original berserker, it took me half an hour and about 9 deaths on Veteran.
Sorry for the self-congratulatory tone of my post! I put quite a bit of thought and time into this and I have yet to come across anyone else having a similar build, so I'm a little bit proud.
