Just want to pop by to say:
Keep in mind that a lot of hits isn't necessarily a lot of DPS, the reserve is also true -- a big hit isn't necessarily a lot of DPS either.
I see a lot of numbers, small numbers floating through, sprinkled with a few bigger hits, and sadly it looks like wisps are the contributors of that small number flurry (these are numbers less than 100 damage). 100% weapon damage is great -- unless it can't crit and doesn't modify off of Attack % and its something to keep in mind.
I also don't see Static Cage getting over 500 damage, which is fine, but from the way you speak in the video -- its the build's bread and butter, and more damage is coming from Cassandra Comboing off of your Shocked with her Shield Bash I'd wager.
Play around with the gear, try and grab Hidden Blade Masterworks or On Hit effects, as they could really drive the damage up even more considering all of the damage 'hits'.
Hope this helps 
Eve
