Call it a keychain since it has too much stuff on it. Couple options from changing out the ERMLs, but honestly once range gets closed it's better to still reach without waiting for the ERLLs to fire and cooldown while spewing LRMs. Ideally the close-range weapons don't get fired until you've stripped the enemy CT of it's armor. Each type of weapon gets its own group, chain the LRMs. Alternatively eliminating the TC1 nets you another ton of armor. Or use a TBR-D left torso as such, for an in between the first two; Improvements welcome and suggestions wanted!
