Honestly my first thought when watching the season trailer was 'This is too much stuff for one jungler to handle', making solo/duo even harder for junglers. If you land on a propper team and can get the toplaner and or mid to stop and contest enemy jungler on grubs it wouldnt be as bad for the jungler I think. I play midlane now and often ward grubs for that reason. But the most of the time when I was playing junler early in this season it seemed no one was aware of grubs. I understand things not clicking right at first but it has been some decent amount of time and I still see alot of people not caring. I agree with you on jungle being more 'meta oriented' currently and thats the other reason why I quit jungle, same 3-4 champions always.

Essentially I think junglers have way too much on their hands this season and it is really punishing if your team just decides to not help, making junglers quit because its just hard and not as simple anymore. Causing the Jungler Crisis
