Remember I'm playing seasons. Not going to level up a WD just for that Non season, maybe, but still, Winged Assassins don't come alone ... they sometimes are quite a lot and Hex is not going to turn them all into pigs. Also, not sure if its fast enough to turn them into pigs before they land cause they even go thru Slow Time bubbles. They get stunned when they land but u already got hit and a bunch of them landing on u will cause some serious damage, if not kill u.

BTW, did some testing and Blizzard Lightning Storm does add a 15% lightning debuff from ALL sources. That's for the whole party, but only for lightning damage. Not sure if 15% lightning damage will add more dps to the party than just having that wizard with Meteor Comet. Still, useful info.
