Hi Commander,
Don't know, but still bothering me is that there is so much crammed in on those platforms. Almost every cruiser has 5 weapon hardpoints. How many are there on the Tau cruisers? A lot more. Same point cost as the Tyrant. Way more manoeuvrable. And that race is still a little behind the IN? It doesn't 'feel' right. And I am repeating myself I know it's not going to change but keep it in mind?
You cannot compare an Imperial ship to a FW Tau vessel regarding hardpoints, though a Lunar has 5 and an IN battlecruiser 6

The race is not behind the IN. Doh. This fleet feels really as it should.
Lunar vs Protector
180 vs 185
8 hits vs 6 hits
Same armour but Tau prow armour to be taken offline in case of critical
2 turrets vs 3 turrets
20cm vs 20cm
45* vs 90*
2 shields vs 2 shields.
So in the basic we trade off resilience vs manoeuvrability.
When comparing tactics one has to keep in mind fleet tactics. 1 launch bay won't overwhelm the Lunar. 5 missiles won't break it. Neither would 6 torpedoes break the Protector.
8 batteries plus 2 lances @ 30cm from the Protector does out-edge the 6 batteries plus 2 lances @30cm from the Lunar. The Protector also has extended range.
Once the Lunar makes it past the prow, even 90* won't help the Protector to keep it up.
8 vs 6 hits is a big deal.
In essence both ships have simple doctrines.
I see balance, especially as the Protector is more expensive.
