The OP acknowledges the problem, a deep-rooted underlying mechanic that makes certain damage delivery systems exceed others in efficiency and power. And then promptly ignores the underlying mechanic that is problematic in the first place, in favor of targeted mechanical fixes that have gross effects on the game he's not playing.
Ghost heat on 2 C/ER PPCs? Where is the Warhawk now? Where's the Dire Wolf B? It's already challenging to keep these 'mechs from shutting down and still sling respectable damage, why make it impossible? Let's not even mention the Adder Prime, which suffers not only from low armor and low foot speed but would also eat massive ghost heat.
Furthermore, where is the ghost heat for 2+ IS PPCs? These are clearly the dominant weapons in the current top tier game, so why not bring them back to parity?
If you do, what happens to the Awesome?
Oh yeah, that's right, the Awesome and the Warhawk aren't competitive tier 'mechs, so they shouldn't be considered in any balancing decisions. The fact of the matter is that competitive players don't think about these 'mechs
at all, except maybe on pug night for the luls.
So forget the 'Mechs and forget the weapons. They need balance tuning, fine. But the problem expressed here is ultimately a game mechanic that creates dramatically different tiers of chassis - pinpoint damage. The ability to lay down all of your weapons on a single point in a single trigger pull is the root and core of the power of PPCs, clan or not, especially while engaged in peeking actions such as jump jetting and rapid cornering. And that game mechanic is what needs to be addressed, not the Timber Wolf's (or the Victor's) nimble torso twist or the C/ERPPC's ghost heat values, or the amount of damage you take to the feet when you land. All of those bandaid fixes hurt other 'mechs and other tactics far, far more than they succeed at reducing the viability of the top tier jump sniping metagame.
The consequences of the changes in the Original Post reach much, much further than tournament play, from lore monkeys like myself who think a Warhawk Prime without 4 PPCs is just a disappointment, to dedicated brawlers who are just disgusted with the dominance of jump sniping. Also, understanding the consequences all the way down the ladder from the scrubbiest newb who doesn't know why he got LRMs all over his face when he was just capping Theta on Terra Therma all the way up to tournament winners will also help reveal why more tactics never even have a chance to reach the upper tiers of play.
