First this is not a build post but I have included potential example builds.
I am going to say I don't think it's an ordinance fix because it make turrets, HLCs and other weapons better too and since most people think the point efficiency of the other options are already better than ordinance then the additional efficiency added by the XX-23 adds to both ordinance and the other options.
My thoughts is that Lt. Blount might seem more play with the XX-23 as he is the most reliable ordinance carrier to guarantee the hit required to trigger XX-23 or maybe something like this with Bandit Squadron Pilots with Munitions Failsafe.
