Unless all weapons do this same splash damage it wouldn't work to balance anything. You would just remove the PPC from the field of play.
There is nothing wrong with the PPC. The most used weapon in MWO remains the Medium Laser. The most powerful weapons in MWO are the Autocannons. What you are seeing is just that most mechs can carry a PPC and most mechs can't boat AC's or Medium Lasers. If I could fill my Awesome with Medium Lasers I would drop all the PPCs and carry 12 Medium Lasers. I think that's a Blackhawk loadout actually (in case anyone thinks it isn't done).
Beam duration on Large Lasers is too long for them to be used at full ranges. So you might as well just take medium lasers, so MWO is Medium Lasers and PPCs. Fix large lasers correctly and the PPC goes away. Poof! Leave large lasers as they are and not many will use them, forcing then to use PPCs instead.
Autocannons are waaayyy overpowered in MWO, not PPCs. Autocannons just fire away every 2-4 seconds and never stop. PPCs overheat pretty quickly and stop firing. Just bring enough ammo and you AC is super-powered with 2xRecharge. I can't take anyone seriously who would nerf PPCs but not Autocannons. Balance is not what you seek.
PPCs can compete with Autocannons till they overheat though, so there is some harmony, if Large Lasers had a shorter beam duration to go with their longer range, they would come into balance also. Large lasers are potentially better than PPCs, but with the long beam duration you might as well replace them with Medium Lasers since 300 meters is the maximum effective range in a moving battle.
