Sorry, it doesn't have auto aim!

They could always go the GC route with ties I guess...
Also, perhaps its good that the air speeders will have a advantage over the imp ATATs, since in the movie it was the troops moving in through the tunnels and the ATSTs that really brought them victory.

I don't think that the rebels will have any advantages.  The ATAT armor is very thick, they are incredibly difficult to stop, so the rebels will have a tough time defending that shield generator.  And after the shield goes down, the orbital bombardment (artillery) starts raining down, and then its a battle for the inside of echo base (it would be suicide to try to maintain fixed uncovered positions under artillery fire).  Once the battle moves to the base, I think it will be pretty evenly matched.  The rebels might have a small advantage because they are able to spawn inside the base, but the imps will most likely be able to spawn inside the ATATs, so they will be close as well.  Ah, it will be a great day when we are able to play hoth.
