Why jungle is so gosh darn unpopular to low MMR players:
Bc there are no in-client Riot based resources/tutorials on what jungling is !
Probably bc jungle is subject to change but like, you could story board a pretty simple jungle path tutorial : (Red Side) Blue Wolves Red Krug as J4 then like have him gank top with some forced quick time event where he gotta mouse over E Q the enemy and he dies like wow super ezpz you did it GJ! Thats jungle in a nutshell!
Also i know there are online sources for this, but make a SMITE simulator (Practice smiting baron etc) ... i know some HIGH mmr players that need this... huehue
