I'd love to see a Mon Calamari map.  Preferably with little Mon Calamari power boats which you could use to ram into landing Imperial Shuttles, sending them spinning and skimming across the top of the water as their crews are thrown out the open side doors.

I think a great map is one where there are lots of buildings you can explore and open areas that you fear to go into. Eg the teams start at opposite sides of a town, the town being shaped something like a rectangle. At the centre of the town there is a large square with a ring of interconnected buildings around the square. There would be a cp at opposite sides of the ring of buildings. There would be a constant exchange of long range fire coming across the square from the opposite cp buildings while there is house to house fighting inside the ring of buildings. There is no way around the square so you must either bravely traverse the diameter of the square or fight through the ring of buildings. Once you controll the whole square there is street fighting between it and the enemy home cp. I got the idea from the multiplayer map, Sniper's Square in medal of honour european assault.
