Do people like the never ending scale champs?

I have always disliked Nasus and Veigar, simply because they don't have to win lane by any margin, and at some point if someone doesn't babysit them, they start to get really strong. Does anyone else think these kits dont really belong in the game overall? Just to do my personal pros and cons

Pros:

1. They teach how to farm
2. Wave management

Cons:

1. Often times the kits promote nonstop splitpushing so players wont group
2. The kits are overloaded into one skill and slight changes to any of the other make the champ busted
3. Babysitting/Unfun to play vs.

Also, I dont really care about the "Win before they scale" comments, because I am sure anyone that is below Masters has destroyed either one in lane, went to help team, because no one was babysitting the Nasus he comes out of no where with 600 stacks and blows your team and 3 towers at 35 minutes.
