That still only accounts for one bullet hitting the squishy bits. What if all three bullets from your burst hit the squishy bits?
My complaint here is that there is no mechanic to account for more than one piece of high velocity hot lead hitting the target. An LMG on full auto, with fully compensated recoil, SHOULD, in my opinion, be able to deal out HUGE amounts of damage to a single target, as six or ten bullets hit flesh. A Trog with an Ingram on a gyro mount should be something to fear. As the rules stand right now, my current Orc Sammie is rolling a lot more than 9 dice to dodge. Yeah, that's a huge penalty, but one or two hits on dodge will help reduce the amount of damage dealt, and he definitely has enough Bod and Armor to reduce the rest down to a manageable level.
Assuming the Ingram wielding Trog in question has a 5 Agl and 5 Automatics, with a wireless on smartlink, that's only 12 dice for an average of 4 hits. If we make him on the same level with my sammie, we give him 6(

AGL and 8 Automatics, so with the smartlink he's rolling 18 dice for an average of 6 hits, and with the Ingram's Acc of 5(7 with smartlink) he gets to keep all 6. That's a pretty nasty hit, but let's see what my sammie can do.
Rea 5(

+ Int 4 means 12 dice to dodge, lose 9 for Full Auto, leaving him with only 3, for an average of one hit to dodge. Damn. That means 5 of the Trog's hits add to the Ingram's 9P damage for a total of 14P damage. Sammie's Armor Jacket of 12 and + 2 for Bone Lacing mean total AR of 14, and considering the Ingram's -2 AP that's fully physical(Now, if he my Sammie has had that shiny new cyberarm installed with +3 Armor it suddenly becomes STUN). Bod of 7, 14 Armor, +2 Bone Lacing, +1 Toughness, and 24 dice on the soak roll for an average of 8 hits. He only takes 6 boxes of damage, 5 once you add in Platelet Factories. That certainly hurts, but that's 6 boxes of damage from a full burst in short range from an LMG. He pulls out his heavily modified Ruger and shoots the Trog in the face for about that much. Well, maybe not THAT much, considering the Troll's high Bod. Had I been clever enough to suppose a human wielding that LMG, then yeah, Sammie does more than 6 boxes of damage on his turn. And oh, lookit that, just read that Gyro mount only reduces 6 pts of recoil. 1 pt free, high Str, and gasvent certainly compensates for the rest, but a second round of full auto will suffer more penalties than my sammie has from wounds, so second initiative pass favors my sammie. If that Trog is a human and is NOT on the same level as my sammie, with AGL 4 and Automatics 4 and I'm looking at even less damage.
Now, if we look at the same scenario where that Trog fires Full Auto Narrow, and while my Sammie now has all 12 dice to dodge, he's facing an 18P DV(Ingram DV 9 + 9 for Narrow burst). Average of 6 hits from the Trog, total of 4 for my sammmie(average roll on 12 dice) means two net hits for a total DV of 20P. I'm down and out with a final result of 12 boxes of damage even after my average roll of 8 on the soak. And even with that shiny new cyberarm it's gona be all physical, now way to avoid it.
As the rules stand now, my sammie knows he can take a point blank shot from an LMG and survive. In our most recent game, a human merc my sammie had pissed off previously jumped out of the back of a van with an LMG on a Gyro mount. This was the last session of 4th we were gona play, where Narrow Bursts still happened. I had to spend Edge to go first, quick draw my Ruger, and double tap with two rounds of APDS, Edge was added to both rolls. I laid him out dead before he could even pull the trigger. I was willing to spend three points of Edge to do it too, because I knew full well if I didn't that Ingram could easily kill me on full auto.
