I cant do it :(
I tried both builds in the OP, and I die like 10times each time I try to farm Act 1 keys.
My biggest problem is the split second I get knockback, frozen, vortexed, I get killed so fast I don't have time to react because Im surrounded by mobs, I cant even SS outta there.
Helpful tips to improve???
You shouldn't be dying that quickly with that eHP. Learn to time your SS.
Against vortex, keep your eyes on the elite. The moment you see a white vortex casting effect on the elite, press SS, or just SS the moment you land in front of the elite, quickly recast SP and RF again.
Against frozen, time your SS to the split second before the frozen orbs explode, which is fairly easy to do with SS:Lingering Fog cuz you have 0.5 second extra so you can SS slightly sooner to play it safe.
For knockback, I wouldn't even bother with SS with that eHP. Just land, recast SP and then resume RF, unless of course, you land in a molten explosion radius or near the apex of an arcane laser.
If your problem lies in resource management, consider dropping MfD for a hatred generator like Bola:Bitter Pill for a more forgiving gameplay until you get more comfortable with the build and find yourself falling back on the generator less.
