I would prefer if they are normal turrets. Make the use of them a choice, not something you put on all ships for free.
Actually, I would want Anti-Fighter turrets to be separate from the other turrets. Warships from around the time of WW2 had the main armament and the anti-aircraft armament, which usually wasn't used on other ships, but on the fighters and bombers that were becoming more and more of a threat (kind of what we are seeing in Avorion). Also, there were many more AA-guns on almost all warships than main guns. I just think it would be awesome to have many, small, close range auto-turrets that are purely for fighter defense besides the main turrets. It could make combat look more chaotic and exiting.
