I propose making transitioning between tech tiers, more dificult , having in mind to reward players with map control.
I can't say if it is a good idea or not , or if it has even be discussed.
It could be experimented with, I suppose.
The way things are now players are allowed to not expand adequately , yet being able to transition
to higher tech. Not only that , but being able to produce at large amounts.
Teching factories and mexes should be more expensive imo.
