[HC/SC] NiceBuild's Mjolner Build 2.0.4+ - Uber viable

You don't get any Max Res Bonus from Purities after level 23. So why are you using Level 21 gems & +3 from Empower & +2 from Alpha's Howl ? What's the necessity here for a Level 27 Purity? I'm sure you can cap your resistances without them?

Wouldn't it better to use a devoto's devotion instead of the alpha's and run an empower? Which will achieve same max res with better movement speed/dex etc?
