[Gameplay] Shacos new passive = debuff for himslef in mid/late game

So shacos new passive will let him crit every 3s with 145% when attacking from behind. With IE the number increases by 50% to 195% crit dmg.

If i assume IE and Statikk Shiv, ill will crit with 50% chance anway - therefore attacking from the front will do 250% (!) dmg whereas attacks from behind will only do 195% (once every >1.5s due to the passive cd!). I know you only have a 50% crit chance from the front, but with the fast attack speed this will most likely happen at least once and youll do 55% more dmg with each crit.

So whats the point of the new passive? A debuff for shaco in late? Its actually completely useless if attacks from the back do less dmg than attacks from the front!
