Going through the top 16 lists I see one single use of ordnance. FFG just doesn´t seem to find a way to make ordnance competitively viable.
I think that TLT hurt the viability of ordnance. K-Wings and Y-Wings are both more likely to spend the points on TLT than they are ordnance and Punishers and Bombers get torn down too quickly to be worth the points. Also, ordnance seems like it is stronger against two ship lists which were in short supply in the Top 16.
...so, imagine that instead of TLTs, you were throwing cluster missiles--cluster missiles you paid four points for, and which did nothing despite having every reason to murder the bugger just because the dice said "**** you"
... I still got into a situation at a local tournie when the dice decided to never roll above a hit, modifiers be damned, and his green dice refused to roll blank. That was a game lost completely outside of my control, completely because of dice. No amount of blocking, re-rolls, focus amounted to anything, and because Redline's munition based he became useless before he died
So what you're saying is you need reliable ordnance, say something that can get around rolling blanks on attacks. Something that will do damage against the ficklest of green dice...
It sounds like you're looking for an Advanced Proton Torpedo.
OR Concussion missile, or Homing missile.
In HotAC, I'me flying a T70 with Proton Torpedos and Weapon Guidance, the torp auto focusing and the upgrade hitting with a blank.
I'm hoping the Guidance Chip in the TAP blister pack does something similar
