Nasus's "weak" early game.
It doesn't exist. As early as 10mins he is capable of handily 1v2'ing even the strongest of duelists.
Nasus is supposed to be a late game hypercarry, not a hypercarry by 9minutes. Nasus should be the opposite of WW. Useless for 20minutes and oppressive after 20mins. Whereas WW is oppressive for 20mins and useless after 20mins. Nasus has no window of weakness anymore and it needs to change.
because can't he stack his Q on the tentacles? I mean as far as fighting 1v1, I can see Illaoi easily winning it, but Nasus usually doesn't care about fighting some one 1v1 but just stacking Q until he can outscale them or until mid game.
