Once your team's jungle is overrun, are you expected to ever take it back?
Just lost a game because the entire enemy team decided to permanently ward my jungle with double Sightstone and upgraded trinkets. No matter how much you try to clear the wards, more will replace them, and in some cases you'll just get ambushed and killed for even trying to move away from an inhibitor turret. Even if your teammates spam wards to try and establish vision, they will kill them all because they see where you drop them, so their sweepers can't miss.
Best part? You can't counterinvade their jungle because you have to cross through enemy-controlled territory and hugely overextend. Bottom line, you're kinda fucked.
I'm guessing this is intentional, but it's especially bad when you're a jungle tank. Fall behind, stay behind.
