Ships that the ordnance fix does not fix :X-Wing, Z95, A-Wing, E-Wing, YT1300, YT2400, Tie Advanced, Tie Defender, IG88, StarViper. So it helped 5 ships to some extent, but did not help 10. On 4 ships it only helps 1 slot. The Tie bomber is the only one that it gets help on multiple slots. Is that correct? If so is it really a fix.?
The a-wing got Aces, The Yt-1300 is still a very powerful hard to take down ship with a lot of HP. The 2400 is a great turret platform with open options during the squad build process. The IG88 Uses cannons, period. The E-wing is a very powerful ship focused on survival and doubletap or support. The ships you mentioned (TIE defender aside) don't really need much of a munitions boost because they don't rely on munitions as their primary form of attack.
