I have to admit, I thought that it would be interesting to have the Raptors go into the space areas and be able to perform actions. If only being used for sensor jamming or what-not, they could slow the progress of oncoming raiders or heavy raiders (or disrupt attacks from a basestar). However, most of the time they would just be defenseless targets - and I'm not sure if the benefits would outweigh the risks. At some point I decided that its just better to use them as 'ship-shaped' tokens, instead of having a use in combat. As was already discussed, maybe it would be better to expand on the already existing mechanic of risking the raptor to have an effect instead of having wave after wave of raiders able to shoot them out of the sky.
