The Nova Cat runs like 20 DHS on most variants - it can handle its enormous heat output. A Blood Asp with paired Gauss rifles wouldn't be able to afford that kind of heat efficiency. "I could do it in MW4" is not a very good example for a build that would work. Even if you assume two-ton HMLs, that's still eight tons turning into twelve if you swap the lasers for PPCs - not going to happen unless you remove heatsinks or armour.
Let's do the maths, yeah?
Blood Asp Prime has 2x cGauss, 2x cMPL, 4xHML, a cSSRM6, and 18 DHS. For the sake of argument we'll assume that the medium lasers are all 2 tons and every ammo-linked weapon has a free ton of ammo. Itemised, that comes to:
2x cGauss: 24 tons
2x cMPL: 4 tons
4x HML: 8 tons
1x cSSRM6: 1.5 tons
8x DHS: 8 tons
You want to add 2x cERPPC (6 tons a pop) and 1x ATM-6 (3.5 tons). So, you need to make 15 tons of weaponry and HS disappear.
Kill the HMLs and you're only halfway there; losing the cSSRM6 gives you another 1.5 but you'd still need to ditch 6 DHS in order to fit that loadout; that'd take your heat load to 14 SHS equivalent. Given that the Adder prime runs 5 DHS (for 20 SHS equiv) and can't really handle its heat in a protracted firefight, I don't see how having more heat (thanks to the ATMs) for significantly less dissipation could work out as anything other than a disaster.
Tweedledee and Tweedledum, this is not reality just a game that is for fun, there are some of you stressing about weapons load-outs by the ton, what we get is up to the developers and what they have done, so we can fight great battles and live to tell the tales of daring do and great great deeds done!
My friend your "Geek" is showing, my suggestion is have a Coke and a smile and remember that this game is a labor of love from the mechwarrior gaming community that is truly free with only the investment of the Crysis Wars game and not having to buy gaming "Gold" like most other games and not a piece of crap from Microslock or the other fallen flags of gaming that have had the "Rights" to Mechwarrior and all of its parts. Therefore, my suggesting a dual Gauss and dual ERPPC with a single ATM(H) 6 or 8 which is the only center torso mounted weapon and the right and left torso weapons slots could either be used for extra dual heat sinks or small lasers or MG.
If you look at the load out I put up I did not say heavy lasers which are heat hogs but medium pulse which do run cooler than heavy lasers and the entire weapons package would be run in a chain fire config by a smart warrior and would not be something to stress over. Hell if you are worried about heat remember the ERPPC's are arm not torso mounted like commonly found in IS mechs and the transfer of heat should not be as great as if they were torso mounted and the Gauss are also mounted on top of the shoulders at the highest points of the mech, again not torso mounted so all of their heat would not be radiated down through the mech along with their fairly slow reload rate they will not be melting barrels anytime soon.
Standing still like a turret emplacement would also cause heat problems of its own, however, the actions of moving from firing point to firing point causes airflow over the arm and shoulder mounted weapons that helps heat dissipation taking into account the map temps this config would be harder to use on "Hot" maps as opposed to "Cold" maps. A choice of weapon con figs when going into a drop should be matched to first if you are going to use Battlemechs or Omni-mechs then the particular mission type for each mech, Brawl, medium, long range or fire support then map terrain, map temps, firepower needed and the preferences and capabilities of the individual warriors assigned to the mission. This is what any good Drop Commander does before taking his troops out to do battle against enemy units.
Since we are not doing league team drops yet, this is something the individual warriors must take into consideration before marching into a fight so he or she may be successful in the fight unless of course you are a noob rush fanatic then all bets are off, rush out die, re-arm, rush out and die, rinse spin do it all again.
