Tank junglers don't have enough income generation or XP to function as such.
The XP changes not only made it impossible for you to function as a tank against mid and top lane (who outlevel you, and thus cut through you like butter), but the fact is tank jungler clear speed isn't that great either and most of their wavepush is garbage so they can't even soak lanes to hasten the rate at which they can get their items to actually function as tanks because somehow their base tank stats are trash.
As a Nunu I simply do not feel like a tank at all unless I get fed 4-5 early ganks to jumpstart my tabis, first jungle item and most of deadmans/thornmail/randuin.
It would help a lot if at least the green jungle item gave mr+armor as well, or at the very least tanks need to have better base stats and per level gains in mr/health/armor.
This is only exacerbated by the fact tanks have to split their income into 2 damage types while damage dealers only need to build for damage and one item most of the time gives them 30%+ resistance penetration.
Please do something for Amumu/Rammus/Sej/Nunu, I'm sick of this conqueror bruiser/fighter or electrocute elise/ekko/nidalee meta.
supposed to play?
though? Are you just going to ignore his existence?
