Again, I remind you, that under the changes to CAF with 2e, AP and TL are just about on a par, so you can look to the Dilgar as guidance. Remember, the Targrath is a bit much right now, so the better example is the.....
Rohric
Raid
Speed 5
2/45s
About 26 Hull and 30 Crew or so (can't remember exactly)
Hull 6
Bolters F 15" 8 AD, AP, DD
Disruption Torpedoes F 20" 6 AD, AP, DD, SL
Pulsars FASP 8" 5 AD
Mass Drivers Never Really Fire Anyways.
Not exactly heaps of dice. If you want to go faster than 5", that'll cost you elsewhere. Interceptors will cost you. Side-mounted Ion Cannons will cost you -- Dilgar ships are front-towards-enemy only, which doesn't seem to fit the Centauri design from what I see on the models. I doubt you will get this many dice, or hull 6, at any point.
The Tourney Targrath was:
Raid
Speed 12
Hull 5
2/45's
32 Damage, 34 Crew
Bolters 10", F, 12 AD, AP, DD
Energy Pulsars 8", A, 4 AD Twin-L.
Zero side guns. You want side guns? That'll cost front guns. Want Interceptors? That'll cost some more.
Another example to think about might be the Chronos. It runs around with 6 AD of turret.
Just saying -- The Centauri players may want to temper their expectations of High AD. I don't know what the final product will be, but previous guidance is here, in a race that already exists.
