It isn't always the Junglers fault
As anyone who reads my posts knows, I'm a jungler by trade and enjoy my work of making enemies wish they weren't left alone with Warwick, making opponents flee in terror from Nocturne, and in general being the person who usually ends up carrying the team. That being said, I've had a lot of games where I have been about as useless as a minion, and rightly deserve to be blamed for stuff.
However, it isn't the junglers job to make sure your lane doesn't lose a tower or make sure you don't get ganked. As a Jungler, my main job is to farm and get experience for team fights, ganking is an optional thing for a jungler to do. You may be the most hated jungler in the world if you don't gank, but it doesn't make you a bad one.
Another thing people tend to blame junglers for is not ganking the opponent that is dominating them and that they have fed. Simply put, I am not going to let that dude get a double kill because I'm a level 7 and he's a level 10, and the person who is ordering me to do this is only a level 5. This is the same person who will then go and blame you for losing the game, and more often than not claims to be a challenger smurf when in reality its questionable if he's even a bronze five smurf.
Lastly, people tend to blame the jungler for not keeping the enemy jungler from camping their lane. To this I say, why would the jungler even bother trying to stop that. The other jungler is wasting time he could spend getting farm, so your jungler should gladly accept the extra farm that he can steal from the opponent's jungle while he's busy camping your lane.
So hopefully you'll read this and go on to understand that it isn't always the junglers fault, that sometimes you have to be a man and own up to your own mistakes and say yes, this is my fault, and not the junglers. While yes, sometimes the Jungler could be brain dead or just having a bad game and a loss could be on the jungler, it isn't always on the jungler.
I'd also like to know what some of your stories are of you getting blamed as the jungler for pretty much everything that went wrong in a game, even if you were the best person on the team.
