There has been much discussion about the wave 3 ships and many would like to see the Tie Bomber. If that is the case then the scenarios need to get closer to the ground. While bombing installations in space might be fun, imagine trying to bomb ground units. Hoth would be great…add some snow speeders (though you could use the A wings) and then AT-ATs etc. and I think x-wing becomes a full fledged miniature universe.
I am thinking of creating a scenario where I make some tokens that represent Imperial land forces that are moving toward the Rebel base on Hoth, while in the air Tie Fighters are trying to destroy various ships as they flee the planet..
Just two of my cents…
