The ghost heat must be removed.
If not, the largest mech that should ever, under any circumstances, mount one is a Bushwacker. They have absolutely zero synergy with any weapons in the game bar flamers and MGs, and as such making a mixed weapon build involving RACs is gimping yourself.
Thats without even considering the buggy nature of ghost heat when applied to extremely rapid fire weapons (If two RACs get out of sync they will activate ghost heat extremely badly.). PGI wont be able to fix the bug, you can tell that because they never could with AC2s, and ended up removing it from them.
Just remove it entirely from the whole family. Its not a problem if a couple of assault mechs mount 4 of them, its only arguably better for the face staring DPS role than quad UAC5s anyway (and unarguably worse for every other role), and the Mauler can run LFE with UACs, and the Annihilator can run 5xUAC5, but only 4 RAC5. Massing RAC2s is crap, they have ~50% of the DPS of the 5s but 80% of the weight, so dont fuss about 6 of them on a KGC or MX90
