A Jungler isn't someone that carries your lane making sure you dont feed your ass off
They are like an extra boost. Sometimes they may not gank because other lanes are priority.
Or maybe dragon control was in their mind so they didnt go top lane.
But most importantly think of them as an addition. They may add to your lane by giving pressure or they may do it somewhere else.
But just because your jungler didn't gank does NOT give you the right to feed your ass off then blame him for not ganking.
Sure there Yi came maybe 2 times.
But guess what you have wards. And you have a support that was meant to help peel for you.
So as a message from a jungler don't blame us because we are successfully helping a lane. If your lane is lost (down 0-4 before their jungler even ganked) then me ganking and you dying is only going to give you a reason to hate me even more.
Junlgers are the new support for people to blame
Sincerely, Your jungler that got our top laner fed
