I think some affixes need changing, There is probably more but this is main ones from my POV.
Death pulse- the short delay needs to increase by like .5 or 1 second.
Drifting shade - this needs an ICD if it has one already it needs to be increased.
Lightning storm - this is the worst affix to me i think its trivial unless fighting an annoying boss. this ability should not happen while out of combat they could increase the rate it happens as a trade off and i would be fine with that. I find nothing fun about back tracking or running back from a death and this ability pops 3-4 times and runs in the opposite direction, it wastes time and does not add value to the gameplay outside of combat
resource burn - just a flat nerf maybe 2% 3% and 4% depending on sigil rank
Im sure there is a few more. Im an iceshard sorcerer btw so thats my perspective. id love to hear others opinions
