As for me they have improved a fair bit but still lack in general usability because they need to be boated much like ac2 to have any real impact on a build. A quad fit seems at the moment to be the minimum and there are not many mechs that can pull that off vs using other more efficient weapon systems.
I've been screwing around with different quad fits on various mechs from lights to heavies and it always comes down to running out of slots and/or tons so you can fit in the rest of the needed items and any secondary weapons.
Damage is fine especially when compared to the tons and slots needed for an ac5 plus ammo and rof is good too in comparison. Heat is workable even with a quad as the extra ghost heat is minimal so you can even run 5 and not get into too much trouble as long as you have the required heat capacity skills unlocked and have compatible quirks.
So for me that boils it down to fittings and it seems that reducing its slots to 1 and reducing weight to 2.5 would open up many more fits on light and medium mechs whilst not making it op on heavier mechs with lots of energy hardpoints and tons to spare. Maybe jinker around a bit on the heat or rof to balance it out?
So thats my take what about you gents?
