PPCs have a sort of weird niche that some people seem to like even though by all mathematical and organic standards they are sub-par to other weapons of equivalent tier. Essentially, they are very light Gauss/AC10 weapons with "unlimited" ammo, but due to the sheer nature of their high heat generation and the cool down period of said heat you essentially end up shooting less than you would the limited ammo weapons in an entire match.
Their ghost heat limit of 2 forces them to never achieve any sort of meaningful damage in comparison to other weapons and even if such a limit weren't in place, their heat is too high and their damage too low so you're always better off simply using other weapons, such as large lasers, to do the exact same thing and damage they would be used for but better. The 3 newer variants are a good step in the right direction but still don't level the playing field enough to make them a considerably appealing addition to a 'Mech's arsenal and are at best situational. Their only real advantage is PPFLD (Pinpoint Front-Loaded Damage) and weight, but Large Lasers weigh less and deal the same damage for less heat and are hitscan. They are basically the skinny man's Gauss/AC10.
Even so, some people argue that PPCs have a place in the game in their current state or are scared that buffing these PPFLD weapons would revive the instant kill wombo-combo blasts and while I don't agree with them I do share some concerns on whether or not it would be possible to strike a balance between making them better and breaking the 'Mech-iverse.
It should be noted that when I propose better stats and/or bonus effects, I am not asking them to double in damage or anything of the sort but a rather sensible upgrade to match same-tier weaponry in terms of overall performance and usability.
As examples, some ideas that were thrown around and could be combined were:
Additional splash damage
Damage over time effect
Secondary damage burst
Temporary map/radar deactivation
Miscellaneous malfunctions
TLDR;
Many people think PPCs are crap. Some people like them the way they are. Others are scared of buffing PPFLD. I think there's room for some reworking to make everyone happy.
