Yes i found that link too, which clarifies about what we have on all hardpoints.
To go back to the original debate of Polaris vs HH, i agree they cant really compare they are very different ships with a different purpose.
But i do think a HH might still caught off-guard a Polaris if it can prevent the polaris to align to fire its torp by going close range and strafe in circle :) (that's another debate, why do you need to face ennemy to shoot torps/missile...) A Hammerhead with 2 or 3 turrets fitted with salvation distortion scatterguns should wreak havok to any large shields. And since a HH can easily position itself to fire with 5 of its turrets, thats 20 S4 guns firing at same time, if half are distortions guns, the rest just need to tear through armor once the shields are down. That is IF distortion guns work as intended (they used to)
on the paper the huge dps with such guns can melt a shield in a few seconds and fry systems at the same time.
