Jungle is the worst/best role
Do you know why jungle is so shit? Because if you play meta then it is the best role in the game but if you don't then you don't exist and have 0 influence on the game. You are literally forced to play those 6 meta champions if you want to win. Doesn't help that jungle has such a tiny champion pool. Other lanes can get champions from each other, so even soraka can be played top but jungle is different and I would really want riot to consider changes to the jungle item.
Instead of pushing Darius into jng 3 times without good results you should consider changing the jng item so that every champion can go jng, which was once in the game but was removed.
Honestly jng is ez if you play meta but if you don't it is the worst experience possible and you wish to die irl.
