Shaco has and always will be broken as fuck in solo que. I agree that he requires a good amount of game knowledge to play properly. I do not recommend to players who are afraid to take risks, can't track the enemy jungler, don't know how to read minion waves, don't understand how/when to spit push, have a weak early game, don't know how to translate early game advantages into mid game advantages, have a weak understanding of how to itemize for a given situation or prefer a farm heavy jungling style.
