Thanks for trying the mod and taking the time to discuss :)
I'll look into the research buffs soon.
Regarding the suggestions, it is very OP out of the box. I tried to give a few decent knobs to turn to dial it in to many users preferences. I'll look into adding the shot cooldown as another.
I do think it should generally be quite a bit stronger than the PLD, especially since they nerfed it in 2.0.
Although I've included options for when to unlock, my personal use is for a very late game equipment that can still hand out punishment to high evolution biters (or modded super biters).
Thanks again for the input.
