How to fix Statik Shiv
As we understand its mean't for wave clear, so I ask why is it so strong for damaging players?
Simple fix: Your next basic attack (on-hit) sparks lightning to up to 5 nearby units, dealing 60 - 160 (based on level) bonus magic damage, increased to 99 - 264 (based on level) against minions. dealing 40 - 120 (based on level) bonus magic damage, this effect is increased by 300% against minions (120 - 360 magic damage). Additionally, Statik Shiv would no longer be able to crit.
This change would make it an effective pushing item and get rid of it's effect of being a lethal poking item. The crit and the high damage was pushing it overboard, besides late game this item could 1-shot minions waves which is pure overkill when you consider the fact ADCs already build attack speed; frankly the crit not needed, bonus damage is enough.
