ok i looked into it to see who was right and wrong. turns out we were both right and wrong. here is what i observed:
-1 targets enemy nrg
-6 targets enemy body
no surprise but this is the only difference in perspective
-1 takes x amount of nrg from foe
-6 takes y amount of body from foe
x=y
this is where it gets tricky
in both shots both body(least of) and nrg(most of) are received in = amounts of the shots(-1 -6) to each other.
that surprised me a bit.
it seems that the conversion rate is about 1 body per 200 nrg received but i'm not sure on that. Botsareus or Numsgil or someone that actually worked on the actual db code to tell you that for sure.
this is where it makes a big difference.
sence -1 shots target nrg there is no conversion but -6 shots target body. in each body there is 10 nrg so with -6 shots you basically get 10 times the amount of nrg than with -1 shots.
-1 shot takes 10 nrg from foe, you get 10 nrg
-6 shot takes 10 nrg from foe, you get 100 nrg
alright it's past midnight and i need some sleep.
