the death of a nation?

[Slug]

What if a nation became all powerfull and took ovr all the continents and the other 2 nations couldnt get a foothold?

well, each sanc has a number of portals they can leave thru

the less land you control, the more concentrated your forces are - at the same time, the more thinly spread the enemies are

And what if one nation has more soldiers then another, eg when one becomes popular.

 

[SilverHood]

it still wont matter *that* much

because the other 2 empires will still be a bit even

Check planetside.com, it mentions benefits that gradually shift between each empire based on hours played by soldiers in that empire. Benefits will (slowly) shift away from the empire with the most played hours ie. a system designed to make it harder for a situation to occur where one empire rules all.
Pretty good idea really, and makes the game more challenging as an empire gets towards the ultimate goal. Also means that if this did happen then it wouldn't be too hard for the two other empires to start taking back land, even if they had less troops.
