Hey, I was talking Dev intent. How dare you get all practical on me! /sarcasm
Your point is taken, but I still stand by Sweep a little bit. Unfortunately, PA can be executed with 1 Stam, and we're doing SO much damage with 1H... The truly practical answer is Sword and Board.
But people keep missing the point of this thread. Yes, we're min/maxing, and posting exploits, glitches, synergies, and excessive optimizations. The point of these threads is choice. by knowing the outer boundaries, you can choose how to play based on what is fun. Is 2H viable? Damn straight. If I can beat the game using Unarmed, any other weapon choice is viable. And that's why this thread and the game are beautiful.
Here's a cause I can get behind. Everyone has individual preferences. Some like steel, others prefer plate, and while I love deadric (yes, yes alien from another world

) I wanted to try something new. Fur caught my attention and I think I managed to hit 75% physical cap reduction with 5/5 Agile Defender + smithing potion + smithing gear + 1 fortify light armour skill. My dark elf's using fur armor + scaled gloves + scaled boots.

That lonely Dunmer from Morrowind is fitting right into Skyrim neatly.
On another note, the destruction perks do contribute well to weapon elemental damage. Are the numbers off? Because with standard fire/frost/shock enchantment on weapons and with Fire/Frost/Storm enchanter taken, we get 31 points per enchantment (*2 with Extra Effect, *4 with DW + Extra Effect). Throw another fortify enchantment potion into the mix and we have 36 points per elemental enchant. Stack that with Augmented Fire/Frost/Shock perks maxed and we get 81 - Feel free to multiple that by 4 if using DW + Extra Effect.
There IS the problem of the 9 perks investment to hit those numbers... (2 more in enchantment tree to reach Extra Effect, 7 in destruction).
All these are on paper though, haven't done the practical tests to see if those numbers are misleading, real or if there's some cap in place. For instance, I'm a little concerned about only 1/2 of the 81 point elemental attacks being registered...
but but...continious shouts would be awesome

Hush, shhh! Don't tell anyone my toon has yet to unlock shouts. He isn't free to manage dragons due to a critical negative reading he had from the stars. Divines have made it such that resistances aren't working this week, so he's not prepared to confront giant fire breathing lizards yet...
