Thanks for the response! Do you mean how an attachment performs on a certain weapon, not on all weapons? For example, granulated grip tape is balanced on most other weapons, but on say the AMAX (again, for example) it performs exceptionally well?
Yeah exactly, our balance/weapon dev teams tend to go after individual weapons holistically to see how and why they are preforming too well (or not good enough). So they'll focus on balancing a weapon in all ways possible, whether that is the attachments for it, individual stats, or other factors.
