Yes, I think the real power will be with more free tonnage to stack exchangers. Since their heat is so high, exchangers synergise with them far better than any other weapon. I believe you can stack a 45% reduction in the basegame. So many exchangers are heavy, but coils are not and I think the real crazy damage outputs will be found with similar build.
exchanger++ : 1 slot 4 ton 20% heatreduction, inverse exponential stackable as i remember ((100*0.8)*0.8)*0.8 ...
heatbank+ : 4 slot 1 ton +20heat max, additive stackable
mounting exchanger in lights/mediums, where space is more available than tonnage, nevermind stacking them is highly situational moreso questionable.
i think coils + heatbanks for everything up to heavys is a better aproach.
and for the concern lights might get 1 shotted, coils are non AI, non MP. Single player only experience, so dont like them dont mount them.
edit: and these things are lategame, you wont see them for 90% of the time youre playing.
edit2 : just math.
edit3: logic adjusted
editX: correction

@Jade_Rook:
Small: 2 tons, 4 slots, 15 damage per evasion (SUPPORT WEAPON)
Medium: 3 tons, 6 slots, 25 damage per evasion
Large: 4 tons, 8 slots, 35 damage per evasion
All versions have heat equal to half the damage.
dmgpotential 1 coil-M = ~0.71 coil-L = ~1.67 coil-S
standard max heat before shutdown: 120
coil-L heat/chevron 17.5 : 150/17.5 ~ 6.86 evasion chevrons
coil-M h/c 12.5 : = 9.6 evasion chevrons
coil-S h/c 7.5 : = 16 evasion chevrons
considering you will mount more than 1 coilweapon, the heabank+ "dmg potential"

is ~1.1/~1.6/~2.67 evasion chevrons
and the exchanger++ dmg potential
is one = 20% (4 ton), two = 20%+16% (36%) (8 ton), three = 20%+16%+12.8% (48.8%) (12ton) and so on..
going from here
https://forum.paradoxplaza.com/foru...rons-explained-need-your-information.1087527/ 6 evasion is max for melee? (i dont now it

)
taking the numbers from above, that means for full potential dmg in 1 shot before on 120heat is:
6 EC:
coil-L 120/(17.5*6) = ~1.14 weapons (for 210dmg per weapon rounded down = 210dmg)
coil-M 120/(12.5*6) = 1.6 weapons (for 150dmg per weapon rounded down = 150 dmg)
coil-S 120/(7.5*6) = ~2.67 weapons (for 90dmg per weapon rounded down = 180 dmg)
5 EC:
coil-L 120/(17.5*5) =~1.37 weapons (175 dmg *1 = 175dmg)
coil-M 120/(12.5*5) = 1.92 weapons (125 dmg *1 = 125dmg)
coil-S 120/(7.5*5) = 3.2 weapons (75 dmg *3 = 225dmg)
4 EC:
coil-L 120/(17.5*4) =~1.71 weapons (140 dmg *1 = 140dmg)
coil-M 120/(12.5*4) = 2.4 weapons (100 dmg *2 = 200dmg)
coil-S 120/(7.5*4) = 4 weapons (60 dmg *4 = 240dmg)
3 EC:
coil-L 120/(17.5*3) =~2.29 weapons (105 dmg *2 = 210dmg)
coil-M 120/(12.5*3) = 3,2 weapons (75 dmg *3 = 225dmg)
coil-S 120/(7.5*3) = ~5,3 weapons (45 dmg *5 = 225dmg)
2 EC ("where did the space on my mech go" edition

):
coil-L 120/(17.5*2) =~3.4 weapons (70 dmg *3 = 210dmg)
coil-M 120/(12.5*2) = 4.8 weapons (50 dmg *4 = 200dmg)
coil-S 120/(7.5*2) = 8 weapons (no mech can mount that much support, 6 max) (30 dmg *6 = 180dmg)
conclusion:
1. the medium coils where the base on what hbs build this weapon.
2. mounting more than 2 coil-l on 6 EC would involve heatbanks (2 coil-l = 210 heat = 120 + 4.5 heatbank+) or heatexchanger, but as said before exchanger = tonnage wich you dont have on fast mechs, or 30 single heatsinks
3. i think
@HonorKnight the
most amazing thread on this forum needs an update (max EC

)
4. someone do the math for max available space on a mech??

5. judgeing the numbers, "boating" them is only efficient if you can "round up" on weaponcount per EC.
