well thats the thing, because if safety was in mind of the ammo stowage, similar to modern systems, there would be a relatively low chance of ammo detonation anyways. Most MBT's and Ammo Carriers for SPG's and Artillery today use multiple fail safes for crew survivability, such as a blast door for example and a blast panel directed outwards for the explosive force to direct. However like I said, it's just an example of what we could add, provided everything is within reasoning of balance other than the typical PVP variables of pilot experience and pilot ability. Sure an FDL may not go with an ammo stowage, but I consider the FDL an Attacker, its not really made for a sustained fight like people want it to be, its made for short term fighting, you drop your payload and you reload, and you can trust on the craft for doing it.
