Currently, one shotting an enemy does not trigger shock. This not only makes several enchantments far less usefull, but also removes part of its identity. I originally played fire mage, and wanted to make a new shock mage. I even made some gear including a very nice exalted chestpiece with 3x exalted overall speed on shock. I was psyched to zoom around with that build… until I tested it an realized if I wanted to get the speed boost I needed to gimp my damage. If I want to one shot everything with no difference in gameplay, I can just stick with my fire mage. So those hours - out the window. Sticking that chestpiece in my chest, hoping for a patch.
In short, what I was expecting: chain lightning from shock taking care of multiple mobs for me, a nice passive speed boost, lower damage because of the need for shock accumulation and speed enchant. What I received: the exact same thing I was playing previously with functionally no difference.
Potential fix: have shock accumulation happen before or at the same time at hit damage. Not sure how difficult that would be to implement though.
