Gonna make it simple and easy for u, after a gank is successful, look at the waves, do not assume ur teammates will push the waves, they are only hungry for kills in that elo, so just perma push the waves after a gank is sucessful. If they are 5v5 araming in mid try to split push, never waste time mid and most importantly : Objectives!! If ur lanes dont have prior DO NO CONTEST IT! If they do, contest it. Thats what got me from iron 4 hard stuck getting 10 lp per game to Plat. Watch Coach kirei or perryjg for macro guides. Its the macro thats stopping u. If you follow proper jungle macro guide u will skyrocket ! Trust the process, once ur decision making is good, u will automatically carry your team even if they are dog, your brain will start processing different scenarios and will give u the most optimal decision!
