No CVs are already exploitable. Just because BAs need a balance item does not mean CVs should also get a piece of candy because the other kid got attention. CVs should get their guns back and that is all. BAs need extra range and Superior armaments because CVs have maneuverability and player assisted range bonus. For balance to work the range and power on these BA only cannons needs to be effective enough to eliminate player isolation of turrets by range and caked on layers of armor. These units could have 3x damage vs blocks and weapons and still may be under balanced for the exploit.
