Switching to discussing analysis of Destroyers, just to make MNB happy

Destroyers Infantry with 25cm move (very good) Skimmers (good), mounted (a disadvantage). AR4+ CC6+ FF3+ 2x 30cm AP4+/AT6+
Great firefight, very good AP (2xAP4 will average 1 hit each), average antitank, poor CC (which isn't really an issue since because Necrons zoom in and out of portals they are unusually hard to charge).
They are 375 for 6, so what else can we compare them to for their main task (fire fighting / AP shooting)? Probably 6 Necron Warriors with a Lord and 3 Immortals which costs a total of 365.
That's 9 units with the same armour, better fire fight (6+1EA x 4+ and 3 x 3+) and much better CC (which shouldn't often be an issue since both formations usually prefer FF to CC, but it's good to have the option).
On the other hand the AP Shooting would be 6x 4+ and 3x4+ instead of the Destroyers 12x3+, so clearly Destroyers are better at shooting anti-personnel, and slightly better vs tanks (they get 12xAT6+ while the warriors & immortals get 9xAT6+).
In conclusion, I would probably take the Warriors, Lord and Immortals over the Destroyers due to the better assault capabilities and increased units for the same price, but since Destroyers have higher ranged damage output the gap isn't as large as I would have expected. The additional assault range and skimmer capability also add other options.
I don't know what your thoughts are but if they were to drop 25pts they'd look more appealing, if they dropped 50pts they'd probably make a lot of lists, but they aren't that bad as they are.
