As for the "OK scale has always been messed up, but now they're just taking things too far" arguments, well why is ranged archers taking it further than hundreds of years for my ancient era army to reach my neighbour? That seems pretty extreme to me. Besides the fact that in all cases other than the few where they happen to be firing over a city or a lake, an archers two tile range will look fine, so long as you don't consider the context, which is pretty much true of all Civ scale distortions - your Chariots may be taking hundreds of years to reach that neighbour, but local scale is kept, because his units are at least moving at the same pace.
Since I've noticed one unit per tile has been brought up I'll mention another thing which is literally never considered by anyone, which I have brought up a few times. It is that improvements have always been one per tile, and this has exactly the same scale ramifications as 1UPT. If people using the scale argument against 1UPT were consistent they would argue for us to be able to stack improvements (more than just road and other).
