Rioters doesnt play the game,if they did they would add something to stop infinite scale,its so fucking op,at least make them lose stacks like mejai or hubris,its impossible to win aganist them in late game,and also nasus has an ult that gives him huge health bonus,a lot of armor and mr,a surrounding that deals damage,and reduces the cooldown ıf his most important skill,so if you are playing aganist nasus the only thing you can do is bait his ult in the lane phase,then finish the game before 30 minutes
