not really, the difference is they Need some time until they can, yorick can splitpush Towers down the hardest in the shortest stage of the game unlike fiora who Needs her items to deal damage on Towers, Nasus who got to farm some stacks and veigar who is more focused on the waveclear than the towerdamage and tryndamere who has enough sustain to tank the enemy while killing the Tower, yorick in one champion has what all 4 of those do. he has good AA damage procs and resets with his Q, he has creeps to hit the Tower really hard and the maiden, he can sustain himself incase someone tries to def AND he can waveclear decently well which in turn also increases his passive power more.
but the Thing is he has only a part of what all the other 4 mentioned champs can do, which kept him incheck so far, but with new rift herald out it became more defined and is, in the eye of some people, a Little out of control.
