A perfect alpha strike weapon then....
Well it still is now, if we're talking pvp

The only difference being you need to dock after every fight or two.
The thing is, heat changes to the game have been significant since launch and have definitely balanced the three lasers so none is better than the other. Yet heat management has made even the rail less effective than it used to be (which is fine) so its effective firing rate is lower.
So I'm definitely for an increase in ammo but also see the potential to simply make it an energy weapon.
Essentially, ammo just forces us to decide whether we should use a weapon at all, depending on how long we want to fight for. The 31 ammo for rails dramatically skews the desirability towards pvp encounters and away from pve. I don't want to have to reload frequently and I don't need to if I use pa's. But if I want to have two rails and pa's on my corvette?
That's what I want. But it just means I may as well have 31 pa ammo, or use rails less, or accept two hard points will be useless after a certain time of playing.
Or just use pulse and multi cannons like everyone pretty much does, because then I can stay out for ages.
