So basically, domination wins should just be scientific or economic wins in disguise? That still contributes greatly in Civ V but at least there is some sense of strategy with 1UPT. Even with a tech lead or greater force, you can still lose if you use inferior tactics, like not softening targets with ranged and not protecting siege weapons with melee.
With 1UPT you can't just smash your troops against each other like you essentially did in previous Civ's.
if the ai was better and there was MUCH more space to manuevre,you will be rigth.however civ V (and hopelly civ :Be will solve this)have a horrible ai,and there is not enougth space to manuver, most figths end with many staltmates in the front will your range attack troopers just kill everything in the front
