I get that a horde's magnitude is not equal to total number of enemies in the horde. I also get that a character can't acheive more hits in a full round burst than the weapons maximum rate of fire. Something I don't quite understand is how the two correlate with one another. How is it possible for a Devestator hit with 3 shots from his heavy and deal 6 damage to the hordes magnitude? Wouldn't that mean that the horde only had 15 enemies in it mathematically speaking? Now, I'm not irked at the system, as I also understand the Devastator's niche is demolishing hordes. However, how should I describe that at least a semi-realistic fashion to my players? The bolts hit multiple people? Maybe they explode in the crowd and snuffs a few guys at once?
That seems to make a bit of sense, but I just don't see how a single bolt round can kill 3 or 4 people on a regular basis. What do you guys think?
