This thread will be fun to necro in three or four years....
I think some interceptor pilots will move to the phantom.
I think the defender will see use as a companion to a small swarm.
Z-95s won't make it as their own swarm, but they'll fill out and flesh out rebel lists in singles or pairs.
The E will join three or four ship rebel builds, but will be less far less viable in pairs or groups than interceptors.
Bottom line is I don't see any of these ships being spammed but they will find their niche as parts of lists.
