Yea that seems like a pretty generic response from EA and doesnt actually address the original concern.
I used to play with the aim of getting all top eight skyscrapers and I had reached pop 400 000 before deciding to bulldoze and start over. But now that im rebuilding and most of my land value is high because of existing services, The only buildings I spawn now are top eight luxurious, and I agree its starting to look too uniform.
So Ive actually started spawning buildings in low value areas then moving them where I like to see them. My old city had an old downtown core near the freeway exit which only had the standard forecast max buildings and it just looked right to me. Sort of a historic district. Also the various mid level condos like willowick are eye pleasing. Also note that as wealth forecast/building grade doesnt affect population or revenue, theres no disadvantage to doing this. All fully upgraded buildings generate equal population and income whether theyre standard, premium or luxurious.
I realize however this doesnt address the original concern and only speaks of fully upgraded buildings. But it is somewhat of a compromise and I look forward to spawning every type of fully upgraded RZs. But I would like to see an option to toggle off the upgrade helmet for those who want to play more for the eye candy aspect of the game and not worry about revenue as much. Actually, an easy fix would be just to have the helmet appear only when we open the residential menu at right.
