Im curious. Actual question not a QQ thread but nasus and veigar why?

Veigar gets infinite scaling with his Q used to have a non target stun that was a bit difficult to land and a nuke that had a huge delay(the meteor) he got nerfed Now I don't mind the changes to his Q .it does make it a bit harder to farm but other then needing to reposition sometimes and put myself in harms way its not to bad given that I can now hit more the one champ with it.

His stun delay isn't the worst of ideas but due to its delay being about 10 years I think it needs a little bit of an adjustment because many champs are so mobile its really easy to get out of it.(recommendation have a delay then after another .5 secs or whatever have it criss - cross in the middle or something.)

Nasus has a target slow (and yes I know his slow was nerfed a while back i'm not calling bullshit on that but it is a target slow unlike veigars stun)

Yet nasus even before the veigar changes always seemed like a better Veigar to me. yea veigar could reach a point where he could almost insta kill even a full tank but nasus can do that too. Veigar was (and still is) made out of paper-mache and glue so a slight breeze could knock his ass over Yet nasus is a crazy tanky mutherfucker who can at a certain point almost 1 v 5 and at least take out 1 to 2 people before dieing unless everyone on their team had a shitton of damage and timed their cc perfectly.

So..nasus is a tanky melee veigar who does AD instead of AP

My question is why was Veigar focused so much(I don't mind the changes mind you) yet Nasus isn't ever mentioned?
