Well what can I say? You guys voted retreat in, it was a difficult choice for us to make as devs.
Getting a new vote would just be annoying.
You know if they add retreat there going to take away something you like. I love being able to reinforce and garrison outposts. A good tactic is to start with one or two conscripts for capping, then later put them in outposts. They can get some decent kills from inside an outpost. They can even repel a flamer. Then just unload, reinforce and jump back in.
