Is there anyway of evenising teams on differant parts of a map, like at one part ( lets say a bridge ) the AI cannot conquer the bridge ( they get stuck in a battle and cannot move forward of back ) and on another bridge, the Cis can take the whole bridge,

P.S i dont want to change the weapons...

I believe you already asked this. The AI getting stuck is due to poor planning.

oh and 1 quick question, how can i lock the planning and barrier hieght, a bridge overlpas another and then the planning and barriers get mucked up

P.s i did already ask the question but i wanted more ways on how to do it, it was a bit vage

Overlapping planning doesn't work sadly. You'll just have to move one of the bridges. And if you want to make one side be able to take a bridge more easily put turrets at one end or something.
