I'm still kinda new to pup and experimenting with the different attachments. I've been following String Theory pretty closely but i find even with the gearsets on there and the attachment sets sometimes the dps is kinda low. One of my other pup friends was saying that the attachments im using are the problem because i had better gear than he did .
TL;DR
What attachment sets are you using for hybrid melee/rng, and straightup melee
