Well, this is BF not E@W.
BTW having an A wing slowed down due to heavy armor is just not practical. A slow A Wing would be inferior to an X wing. If Anything you can give it better weaponary.
Then again I am opposed to how BF ducks with the roles of various crafts. They should just let them function as they are in the movies/EU. Some fraction sjust have weaker crafts... You can give them faster spawn time(or even more population) to deal with that, but changing around properties of crafts is just stupid.
