With the Clone Wars coming to X wing, will we see the first initiative 0 pilots in the form of the droid pilots of the CIS? I'm sure that the best ace pilots for the faction will be the sith assassins (Maul and Ventress); there will also be much stronger droid pilots with higher initiative, but the CIS deployed droids en masse in a cheap and cheerful way (even more than the empire did with TIE's).
I'm not sure if it would break the game, but it seems like a very cheap droid with no sense of self-preservation would be a lower initiative than a living being who is still learning how to fly, but would like to continue being alive.
