its not always that simple.
Is your mid lane losing? Does the enemy mid laner have a crap ton of agency? If so, the enemy jungler is cruising on his mid laners presence, is going to pull far ahead your jungler, and your jungler is going to be forced to be passive and/or reactionary, rather than proactive.
Just because youre getting camped, doesnt mean your jungler can help you.
You need to look at the map as a whole, not just the situation in your own lane before you criticize your jungler.
Example: is he significantly behind because YOU didnt assist him at a Scuttle skirmish, where he ended up losing scuttle, taking a bunch of damage, and losing half of his jungle because he had to recall? Because the enemies team assisted their jungler, but his team didnt. Spiraling him into losing his role.
the jungle is very sensitive, we need help from laners.
its much easier for us to help you, if you support us when you can.
But most players below high plat dont know or understand what jungle priority is.
