>>17748684ok dumdum listen up ill give you the quick rundown
top is a solo lane right, thus you have one toplaner
same goes for mid
then you have botlane, where u have a support, supporting the adc meaning ATTACK DAMAGE CARRY, right?
then beyond the 3 lanes you have the jungle filled with monsters, buffs, on kill vision giving mobs, whole team buff giving dragons and the rift herald / baron, thats where the jungler becomes necessary, also when you jungle of course you keep an eye on all lanes at all times and the moment any enemy over extends you stomp their shit in if you are close enough
