I was looking at the damage tables for weapons and noticed that SMGs have a different progression then other weapons.
I can dump my tables if it's easier to set out, but essentially all weapons (bar the SMG) gain an additional point in "spread" when going from Laser to Magnetic, while the SMG doesn't get the additional point until it's upgraded to a coil. The effect is that while every other weapon gets an "extra" 3 points of damage when going to magnetic, the SMG only gets 1.
It catches up in Coil but, to me at least, it would be better to have it the same as all the other weapons.
Hopefully this hasn't already been discussed!
