....but never HBL. Or Paladin PD.
Same.
The small Burst Laser is better for a lower cost (both OP and flux), so I always prefer to use small energy mounts for PD wherever gives adequate cover and leave the medium energy mounts for ship-to-ship guns.
Downsizing the mounts is also something that happens a fair bit for medium energy, just because the the HBL is so underwhelming when you want PD.
The Paladin is fairly unique in that it has possibly the most restrictive usage options of any weapon in the game.
It's completely pointless in a hardpoint.
Of the two ships that can realistically mount it in turrets (Paragon & Odyssey), neither can realy use it without seriously undergunning themselves and undermining the whole point of fielding a capital.
If you put it in the Paragon's turrets, you've reduced its firepower by 50%, and restricted what's left to whatever you can point the entire ship at.
If you put it in one of the Odyssey's port turrets you again reduce its firepower by 50%, and if you put it in the starboard turret it's more-or-less useless as that side is facing away from most of the threats.
Paladin is not a bad weapon because it doesn't perform, as it's actually very good at PD. There's just no real opportunity to use it.
