Stupid long video for you to review, easy to scrub through. Upload started at 11:00 AM EST, should be fully ready by 1:00 EST.
2 1/2 hours of VotA viewing. Oy vey. haha.
So I watched the first 3 runs so far (I'll watch the whole thing eventually, I promise). Most of the things you're dying to in those 3 runs weren't deficiencies with the build or gear, but rather "user errors".
In the first run, for example, you died 3 times: twice to Molten Explosions (which you don't have the EHP to take), and once to getting frozen (which you might have been able to survive if you slammed a potion the split second you came out of it).
I can't remember if it was the 2nd or 3rd run (might have been both), but you got gibbed by elite Copperfang Lurkers. You really want to go into those fights with Safe Passage up at the start to help stabilize things until EB gets going, and make sure you keep SP up as much as possible on them, because they hit VERY hard and fast (their base attack speed is slightly faster than everything else in the game, at 1 attack every second and a half instead of every 2 seconds).
Remember that although you're running with more healing, you lost a lot of HP going from your 1H to 2H setup, so you don't have that big buffer to pad yourself between hits. SP is the key to making up that buffer. Healing is applied a fraction of a second after you take damage if you're applying damage full time, so even if you had 100% LS and 40k HP, 3 hits at 15k each taken at the same time is going to kill you. So again, try to keep SP up as much as possible on things that you know can gib you like that, or try to get a bigger HP buffer if possible.
You can also try Blood Magic to help.
Anyhow, when you weren't dying to user error (I don't mean that offensively btw, I just can't think of a better way to say it, so apologies), you were killing really, really fast. Looked like your elite kill times were just as fast or faster than with your 1h setup in your other video. The biggest differences in overall clear times are from using only 12% MS and using SP instead of Wormhole.
We're on par when it comes to damage/gear, and with your build, I can't even come close to hitting that speed with your build. Especially 10 elites, and if there are any nightmarish/extra health. In my perfect/undying runs that were especially fast, I could do under 6. I should note that in order to even hit the times I was able to, I had to skip looting and did not start my timer until I hit my first elite pack.
It's highly likely you're just a far more skilled player than my old drunken self. ;)
Nah, I'm just more accustomed to the build. I've been playing it since early this year before they buffed SS damage and before they fixed the bug with Safe Passage, so I've just had more time to play around with all the little nuances of the build is all. So I think you just need to get used to the build is all. Like everything, it just takes practice until everything becomes muscle memory and you're not thinking anymore, just doing.
Also, as I noted, in order for me to get those clear times I use Wormhole. In my personal testing, Wormhole in a 2H SS build shaves about a minute or so from overall clear times in VotA. In exchange, you need to be more careful on elites and stutter-step out of stuff. I should have also mentioned that when I use Wormhole I change my gloves to ones with something like 280 Int, almost 200 vit, 45% CHD, and 10% CC. The extra HP buffer from that extra vit helps with the loss of SP.
One thing that was eerily familiar with your suggested build, is that it acts more like a high damage close ranged Archon build. Use of Explosive Blast is the same as Arcane Blast, but twice the weapon damage, the standard buffs are there, sparkflint, magic weapon, and armor of choice. You then have access to teleport, which, you can spec as in archon, and of course, your channeled spell, sleet storm. It makes sense and it works, but I couldn't get it to behave well, nor did I enjoy it that much.
Yea, it is sorta like Archon. I prefer it over Archon, though, because I really like the 360 degree AoE of SS over straight beam spells, and you get to keep Teleport without sacrificing damage. And 2H SS should be more damage than NON-Improved Archon specs. Plus it's much, MUCH cheaper/easier to gear for 2H SS to do MP10 than it is to get Archon functional at MP10. That, and Archon blows goats in VotA, whereas 2H SS is one of the better VotA farming specs for solo Wizard. I'd argue that it's on par with SNS there if you have the gear to support it.
Speaking of Archon and VotA, check this out if you haven't yet:
SS Archon Destruction hybrid. A really awesome idea that a guy named Heroscaper came up with awhile back when he and I were fine tuning the whole 2H SS thing.
Thanks again for the video and for trying out the spec. The more you get used to it and the more you learn what you can do with it, the more and more efficient you can become with it. The gameplay might not be as engaging as other builds, but it's a freaking monster of a build for VotA farming.
