They are correct. You just need to look for the actual damage modifiers the FT has for specific damage types. In this case, FT has a 50% damage resistance to “small plasma” which is what the whatever name new HHPC projectile is classified as.
I need to test again. TBH, I haven’t found the time and motivation to do so. I’ll need to spun up 3 machines to prove also that LMS applies in a PM with only one FT loaded in.
I also think (I may be incorrect) that bots don’t affect LMS and only real players do. I need to test that theory
