Magic weapon get's me from 21607 to 26143 DPS: that's ~20%.
Dunno about you but my electrocute is super fast because i have 2.6 ATS (attacks per second). Which rune on magic missile?
As for slow time, i placed it ready to try but haven't actually tried it. Because time inside that bubble flows much slower for enemies and much faster for allies, the idea was to do a hydra venom and place that bubble so that the hydra had more time to act: haven't really tested it, though.
Also: can't swap mirror image for teleport because they are from different set's of skills.
The idea behind blur is so that, if i'm hit, the hit doesn't kill me, and them 20% melee sure help.
I was just throwing the 30% guesstimate out there, I just knew it was greater than the 15% it says. but anything will scale with that attack speed, I personally use Seeker on Magic Missile, that way you can use cover and shoot around corners, but the one that does 143% is great as well.
If you have enough movement speed you won't need slow time too much. Even sometimes I can just run in a circle with Hydra in the center and the enemy's just kind run in a smaller circle staying in the poison. A bit more movement speed and I should be able to do that for all but Fast groups.
Also turn on Elective Mode in your options. You can run basically any abilities on any button, if you were so inclined you could run every single ability from the Armor skill set, though they would over ride each other I'm pretty sure. Elective Mode is where it's at, really opens up classes for more potential.
And I understand the point of Blur, but with Force Armor you won't get 1 shot, and with Teleport rather than Mirror Image, you will get away after that 1 hit. So running something that gives your abilities slows will remove the need for the Slow time (since now you will have 2 abilities that slow and do damage on top of that). It will also give you a more consistent slow, you won't be dependent on the Slow time CD coming up, you will just always have a small slow.
