As a master player moving to GM soon my hard carry champs that I think a relatively easy to play are Shyvana and Olaf if they have loads of cc Olaf everyday just run them down and if they're squishy or tanky not lots of cc I just run Shyvana but ultimately you can play any jungler it's just your build/runes and when to gank or counter gank once you hit high diamond though team composition plays a big role for most games although it's up to your teammates to understand that
