The one bigger complaint I have about this game so far is the micromanaging of emptying garbage dumps and cemeteries. Though it seems you can just delete these and live off incinerators and crematoriums alone. I think to avoid the micromanaging if you do keep these first tier buildings and keep them from being obsolete they should be solely collection buildings and the tier 2 buildings stick to automatically collecting from the garbage dumps and cemeteries. This way they all have a role. Until then though it looks like I am going to be deleting my garbage dumps and cemeteries as both my incinerators and crematoriums are more than enough to meet demand.
