How to play when you have a bad jungle player?

Is impossible wins... Jungle is the most important lane

i think it depends, if you are not getting ganked by enemy jungler, just play safe and passive until your laner gets overconfident and makes risky plays on you

Focus on farming, even if you are winning your lane and able to get kills the enemy jg will likely focus on helping their lane.

If your jungle is bad, win your lane and pray the adc is good. you can still win !

be u ur jungler, cuz if your jungle does not have a utility champion you will not win

Play safe on your line, if you can't win your line at elast don't lose it, if you play mid try to roam

Just be better, statistically you'll win more

I suggest warding nearby jungle bushes to somewhat help your junglers vision, and prevent him from getting caught in an invade by the opposite jungler.
