I get your point fugitive but losing a zone would promote a vicious fight' 
Perhaps if the zones had worth of factories or something that benefits that faction/nation/chess piece as a whole. Right now I can take a vbase that is isolated, an airfield by the enemy strats or a port, and they are all worth the same in the required percentage to win the war.
I think it would be beneficiary for HiTech to utilize a system that gave each base or zone a worth of some sort that benefited the attacker in some way (getting resources or something).
Because as it is now, it's simply steamrolling. "That base has a gv spawn into this one, we need to take it!"
