How is the building aspect of the game?

Here is a question for those of you that have Civ5.
How is the building aspect of the game? I see that the combat changes are great, but from what I can gather it seems many of the economy and diplomatic aspects are quite unbalenced. Do any of you think the millitary aspect is the highly dominate way to play right now?

I think so.
It seems a lot harder to sit back and build your way to, say, a Cultural victory than it is to simply pump out quite a few units, upgrade them as you go, and steamroll a whole continent.
Some balancing patches for the production rates and such would be lovely.
