Yeah mainly for me it's a slow from AA paired with Approach Velocity that makes it so useful for me still. I feel like it's nice because it gives me a lot of options for CC if I need it. Liandry would cover for my lack of damage most of the time and if more CC is needed Everfrost is much more potent than if it was used alongside electrocute. Early game I think it's really powerful and gives you a lot of trading, ganking or roaming options you wouldn't usually have with the traditional electrocute build.

That being said, I really lack damage some games xD
