... I will be blunt here,
fapp nah.
Large Pulse Laser 470m (10H) (MWLL 600m)
Clan Large Pulse 952m (20H) (MWLL 600m)

ER Large Laser 905m (19H) (MWLL 800m)
Clan ER Large 1190m (2125H) (MWLL 900m)

That is enough to make me stop playing this game, or at least play it much less, there will be no reason to use ACs or Missiles at all, just a lazor war if that happens. There are some slight adjustments that could be made according to this table i would support, but this insane stuff? Hell no.
The mainstay that must never change is clan LRMs losing minimum range. If that every happened then MWLL would have an accurate translation of CBT in that clan LRMs are incredibly OP.
Why does this bother everyone so much? IS have MRM, clan needs a counter.
Now I could see how directly straight flying could be annoying, but halving the minimum range with a much smaller arc or quicker turning arc for clan would be really nice , it would make their LRM's on mechs like the Cougar prime, and Madcat prime more attractive, while not buffing stuff like the Vulture LRM boat at all, its still a stupid idea to get that close in a pure missile boat. The SRM boat Vulture still has a short lifespan at close range and the refire can be cycled perfectly on those and the heat is very manageable, trying to do the same in a LRM boat would be unwieldy and silly, not to mention futile against anything smaller than a bushwacker.
Heck you could have the larger missile racks spray at first then all gather and arc kind of like MRM do but more pronounced to prevent all of the missiles hitting at close range.
PPCs and Gauss dont have minimum range in this, why should clan lrms?
There are fine lines when it comes to ranges I recognize that, but I think a slight adjustment to Clan LRM should be made to make their jack of all trades designs more workable. Slight adjustments is the deal, when CERLBL got buffed to 900m it was annoying but understandable and I like that they are pretty much better in every way to the IS one now. But 1190m? HELL no.
