ive been looking around in the forums and in guides and a lot of people recomend that when ure starting a bb crew that u should make 2 BOs so that ur gunners are ahead in levels and ive been doing that but now i have one question...
should i pick the same line in the ship tree with both or should i pick different just so i can get all the ships?
if i pick different ships then id have to switch my crew back and forth to lvl both BOs and i might also not like one of those ships but id have to use it to lvl my BO anyways... 
so what would u recommend?
