SK/Mag was the only real challenge honestly, but now that I have it down I'm confident I could one shot it.
I did not kill all 3 without having to kill an extra elite pack, but that was only due to wiping on SK/Mag 3 times.
This was done with the current gear/skills shown on my profile.
Also, I will probably NOT be doing this again, took FOREVER! I think if I one shot all 3 it would probably take 45 - 60 mins to do it again at the very least, depending on how long it takes to get to 5 stacks.
My stats and skills when completed were as follows:
My stats in CM/SNS gear is as follows:
Sheet DPS: 80357
AR: 759 (Physical is 1012, I think this is how I survived SK using SA instead of FA)
My latency is usually right around 100ms give or take 25.
