The Pulse Laser is the definition of a do-it-all generalist weapon. It does precisely half the damage of a Medium Ballistic or Kinetic, at less range, for 50% more flux, but with perfect accuracy, little overkill/decent rate of fire, in one mount and only 10 OP. It doesn't do anything remarkable for good or ill, but that's kind of the point. In a sea of specialization, it does look bad by comparison but truly, it's the ideal generalist weapon.
I suppose if you really wanted to modify it slightly, increase its damage to 150 and only fire twice a second. It would be the same shield DPS but have greater armor penetration. The trade-off is that it wouldn't deal with fighters quite as well and be slightly inferior as a pressure weapon. However, I think the Pulse Laser is overall fine for what it is.
That's exactly why it needs changing. While it may be the most generalist, the nature of high tech ships is such that they have no use for it, since specialised weapons are virtually always the better option for effective loadouts. The pulse laser is certainly not worth 10 OP in its current state.
The new kinetic blaster will probably replace the pulse laser in the few places I use it like on wolf loadouts, which is why the pulse laser needs some kind of edge, since it currently does not have a niche. There are far better missile options for cracking armour especially now that the breach is available.
