Apologies all around. back to the LB's Another major differnece between the LB series and other weapons is BV. The LB-10X as a BV of 148. ERLarge Laser: 249. Lg Pulse: 265 UAC10: 211. All essentially deal 10 points of damage at a max range of about 20 hexes(give or take). The before mentioned ERPPC is in at a whopping 412. The BV diffence is important especially when placed on fast mechs whose speed multiplier will compound this difference. The clan Grendel is a good example: Prime sports an ER Large Laser and its BV clocks in at 2096. Whereas C carries the LB-10X and weighs in at a mere 1422 BV. D config graces us with the ERPPC its BV is 1963. Prime vs C especially telling. Of course there are other weapons gracing the other configs and each has its advantage, this is merely a illustration. It was the 1st omni I stumbled upon that had a LB-10X and another 10 point damage weapon in an alternate config. The low BV of the LB-10X compared to other weapons does hint at it being inferior.
The numbers come from a mech generator I use and may be wrong.
