Nasus; late game.

With so many nerfs aimed at champions commonly played in higher elos and competitive play, I feel like some ridiculous champ designs are being overlooked. My example at the moment, being Nasus.

Now I don't feel like Nasus deserves a ban over many other champions, because others are far worse on a much more consistent basis; but that shouldn't excuse his design being overlooked, in my opinion. I believe in the 'jack of all trades' or 'master of one (or two)' idea, except Nasus is able to tick the box of 'master of all'. I know one can shut him down early game, but as long as you're unable to close out that same game fast enough— you're forced to deal with him in the late phase regardless. How many tanks are there, that're able to soak up so much damage, while having the ability to slow a carry up to stupendous amounts that lasts a very forgiving 5 seconds on top of which, while potentially one or two-shotting them if he's farmed his Q up semi-decently? He just does everything exceptionally well if a game continues on long enough.

I'm aware ADCs such as Vayne work very well against him (I was in a game with a Lucian, who sadly can't shred as well); but am I the only one who feels as though he's able to do everything a bit too well, late game?
