funny that you say pinpoint damage and lasers in the same sentence.
Lasers are NOT pinpoint damage, Lasers are DOTs. These are only pinpoint if both target and shooter are not moving and the target is to stupid to torso twist, in other words its your own fault if only your CT is burned through by lasers because obviously you have
a) not been able to twist.
were moving not fast enough
c) or you are driving a really bad PGI designed mech that is mainly CT on legs (hello jenner) then its actually bad luck that you have bought a lemon.
Lasers are not any problem, because you can, as already said spread the damage and Lasers are already severely limited by heat.
They have roughly tripled to quadrupled the rate of fire without adjusting the damage accordingly (firing 4 times in the same time frame? then dmg is divided by 4 result is damage is more spread). Lasers are some of the few weapons that are actually limited by heat. Most of the other weapons can fire away without problems, so that was the first gimp to lasers, then they made em DOTs next GIMP and to top it off they gave some Lasers absurd burning times that made em actually worthless. So ballistics make massively more damage than in the originally based game and the balance was for the original game.
Next mistake they at least doubled the heat scale. Firing 2 ER-PPC at the same time will normally instantly explode your mech, by doubling the heat scale they made abominations like 6 PPC Mechs possible and for quite some time viable. Many good people left because of that nonsense, and those were people who pay the game that you are playing. Its the die hard fans that rake in the money not the "oh robots cute" guys, the "it a battlemech NOT a robot" guys are who buy the big packs.
To top it of they only doubled the armor which means they have made a severe mathematical mistake from the very beginning.
twiple to quadruple weapon damage and only double armor.... you see anything weird?
TTK is not a problem of lasers, these have always been the bread and butter weapons in BT and Mech Warrior, Lasers are actually underperforming here. Especially weird was their decision to make Clan Lasers hotter right after introducing these. No one complained about the Clan Lasers not even IS people, which made that decision even more weird.
The worst offenders are PPC, Gauss, IS ballistics and Clan Ultra 5. If you wish to increase TTK, tweak these.
Also tweaking heat is a nonissue because the enemy is dead while you are only hot so the right tweak would be simple:
you simply cannot fire PPC and gauss at the same time,
actually you cannot combine anything with either PPC or Gauss. so you would be limited to firing 2 gauss or 2 PPC and then for a second nothing else.
you cannot fire more than 3 IS Large Laser
you cannot fire more than 6 Medium Laser at the same time. you have to wait for a second before you can fire the rest of your same category Lasers.
and so on.
the technical lore reason is: because
(the same reason why ghost heat was introduced instead of simply limiting the amount of weapons that yuo can fire at the same time)
That are your only viable options, anything else means turning the wrong kn.obs and pushing the wrong buttons.
