seriously what's stopping kog'maw
from going into the jungle? just take some tanky runes, get a good first leash, get devourer and guinsoo's and then laugh as you op proc your w for tons of damage on anyone who tries to get close to you
first clear might be hell, im not sure. but with sated later in the game, kog'maw would be so oppressive and overbearing i feel like it's totally worth the risk

are the others) is harder to counterjungle than
?
are all pretty damn easy to counterjungle too
