After taking your red/blue You could gank mid/top ( most gankable lanes) if they are pushed by the enemy team. Usually I am ganking succesfully on lvl 3 or 4 and on lvl 10 I am already fed. Your fast ganks will give you the priority to get fed even by assists 'cuz actually the jungle doesnt need kills. So early ganks gives you early items It is my first build so feel free to Judge me xD
