nunu is just useless...he has no rune to use unless if he goes Ap which it sucks..
His base stats are retarded he have lower armor than adcs nowdays so any jungler can 1vs1 him easily
His clear speed is gone done down by far and he cant even counter jungle any more
He have only one damage ability on a damage meta
This champion is literally Useless right now..there is no point to play him..you could play nautilus and do better i mean nautilus have a rune to use and have some damage abilities and AOE for the jungle clear..
Nunu need rework and riot dosent care because as yous ay nobody talks about nunu so that mean nobody buy skins for nunu
