I remember that variant and rather liked it. The TComp is nice, but having guns to fall back on when you jam the big gun or run it dry makes up for the -1 to hit.
It was exactly as overpowered as using aimed shot with 2+ weapons of any sort. If your argument is game balance then you should be arguing that no unit should be allowed to make aimed shots with more than a single weapon.
I think the benefits of a RAC/5+TC under current and former rules are very pertinent to a Mech carrying only these 2 equipment.I am playing a bit recently with 2d6 probability so yes, I'd like to hear why my math is off, here or in a PM If you prefer :)
Battletech transport rules take a very feline approach to moving troops in a combat zone: If they fits, they ships.
Fun fact: The Legionnaire is one of two 'Mechs that shares it's name with a disease, along with the Septimecia.
