I like the idea here. Just imagining how well this would work with Death Dealer and CP added in. The medium changes are certainly interesting and 3/3/1 is a setup for PVP I have been considering when the patch drops.
Is that low of crit resist in no-cp/proc normal?
Personally, I would prefer Shacklebreaker (with 3x swift mag regen jewellery) over Seducer. It's not a huge difference, but with mag cost reduction from sorc, breton, light armor passives, one cost reduction ring and Seducer all (probably) stacking muliplicatively, as do percentage based mag recovery increases, I'd feel like missing out a bit.
edit: forgot about swift, that's a nice bonus for this playstyle
At the end of the video I remove, individually, the seducer bonus and the cost redu ring to show the actual numeric difference, it's pretty significant in my opinion.
