Re: Idea for map
Safe-Keeper: Exactly. The big problem on interior maps is that, if there are only a few ways to get from points A to B, then 4-5 people can simply fall prone, set up a Eweb, and have a ball slaughtering incoming opponents. More corridors, and that problem evaporates. For a problem case, see: Titan Mode.
I would suggest, however, that the map be at least a Push map. I still like the idea of running to the escape pods, because it would thin out the number of fighting Rebels and give the map a feeling of an overwhelming number of Imperials against a scant few Rebel troops. If we do go for something more tame, though, make sure that it's Push or the Imperials will be unlikely to get far.
And detpacking the door would be an awesome touch. Give it a custom death animation, and we can get a nice Battlerecorder recreation of the movie.
