Can Junglers Be at Fault?
So the most common debate I've seen so far in my short time in the league, covers the topic of junglers.
I understand a few things about the jungle role:
1.) It is not their responsibility to gank
2.) They are allowed to afk farm in the jungle as long as they take objectives, such as dragon, etc.
3.) And it is not their fault for my deaths in the lane.
However, in every video regarding this topic on YouTube, it always portrays that the jungler cannot be at fault for anything. But, I don't seem to buy that, as I feel there isn't a logical way there can be a position where literally anything they do is 'okay.' So I unfortunately have a few circumstances where I'm unsure if I'm allowed to be frustrated with the jungler justifiably. In all of these situations, this is before the laner has died, or has only died once.
1.) The jungler afk farms in the jungle, does not take any objectives, such as Dragon, or Baron, and only comes in to lane when their laner has died, or left, to either clean up the other laner, or to take cs.
2.) The jungler comes in when their laner is not present, and tries to fight his laner's opponent, despite having a clear disadvantage (Such as level, hp, mana, etc.), and dies. The amount of times this happens during the duration of the laning phase varies starting after one occurrence. (For this one, I can see how the result can vary depending on the number of occurrences, although I'm unsure of how I should judge this factor, so if you could reference this detail if you choose to answer this one, that would be appreciated).
3.) A laner (in an example, me) pings for help from the jungler, due to heavy lane pressure, and would like him to help with this. The opposing laner(s) are pushed right up to my tower for the majority of this. However, he does not do anything, and continues to farm in the jungle. He tries to contest objectives, such as Dragon, and Baron, but cannot due to the fact that most of the time, his bot lane/mid lane cannot support him as they either have to back, or are too far behind to be able to help (e.x. no items vs 1-2 items) and he always has the disadvantage in numbers and power. He also does not gank any lanes and/or only ganks one lane, and primarily focuses on jungle farming.
In all these situations, I did not consider the fact that the jungler was a devourer jungler, however I feel that this detail may not be entirely relevant, as even if the jungler is going devourer, they should be actively going for dragon and baron, as it gives them 5 stacks each, and I'm okay with afk farming as long as they do go for these objectives. Also, my mmr currently places me against Silver, Bronze, and Gold players, although this factor may not be as entirely relevant either.
I also just want to state that I'm not looking for situations where I can blame the jungler, but I am looking for situations where I can feel justifiably frustrated with the jungler's actions, and perhaps feel they could have done something more. If I feel that the jungler is not at fault, or could not have done anything to benefit the team, then it is easier for me to be able to let it go and accept the responsibility of losing. Also, if there are any situations that I have not mentioned that apply to this post, I would appreciate knowing those aswell. Thank you for your time in reading this awfully lengthy post, and I hope you have a splendid day. :)
