As the jungler, if I get invaded and get no help from my laners
Then I won't be ganking for you. Ever.
I don't give a fuck about your farm, or how much you're dicking your enemy laner. Jungling is a 2-way street: I help you through ganks and objective control, and you help me when I get invaded by the enemy jungler.
Honestly, I don't even care if we lose a 2v2 in our jungle. Just the fact that you came to help shows a great deal about how much you value your jungler's presence. A laner who refuses to help because their own selfish needs take priority is a laner who doesn't care one bit about the well-being of their jungler.
As such, I won't give a second though to these laners, and will simply gank for the other lanes. Don't like it? Maybe try playing like this is a team game next time.
