What responsibilities does the jungler actually have?
I remember when it seemed that every game was blamed on the jungler even when it was not really their fault, however I feel like now there has been a strange over correction where it seems like nothing is the jungler's fault and if you say otherwise you will get flamed into oblivion. In my opinions the jungler only really has a few responsibilities:
Farm Jungle camps- This one is pretty obvious. I don't think anyone disagrees with this.
Take objectives- They have smite, and they are not tied to a lane so they have much more time to solo rift or dragon
Gank lanes- Apparently this statement is controversial for some reason. I actually hear people say "ganks are optional" and I can't wrap my head around it. That is like an adc saying last hitting is optional. Yeah it is, just not if you want to win the game. I understand that its not the jungler's job to "win lane for you", but it certainly is the jungler's job to help lanes win. I get that they can't always help every lane, but when if laning phase ends and they have ganked 0 times, chances are they are losing that game.
Perhaps someone can explain this ganks are optional sentiment to me?
