Isn't ICS a staple in TBS? In civ, you gotta keep building cities, galciv, you gotta keep coloizing worlds, heck even in MOM, the godfather of mythical TBS you had some ICS going on.
expand or die. Whats so bad with pioneer spam? I feel that people complaining about that might complain that you have to research technology. I don't see whats wrong with a TBS that forces you to expand while also forcing you to reserach technology, etc. I mean, in Chess you are forced to move one piece at a time, but this doesn't kill the strategy in my mind.
