So if the cooldown of Scrap Grenade is increased from 1s, then what would it be increased to? The Juggler's reload is 1.5s and One Shot Rifles have a 1.1s reload. Increasing the mod's cooldown to anything over 1.1s might fix the OP side of the bug for some who are abusing it, but it would negatively impact anyone who's currently using it properly such as those players using the weapon it comes natively on, The Juggler, and One Shot Rifles. Please consider this before deciding on a backend fix vs a true fix that requires a patch. Thanks.
I won't pretend to have the exact metrics that it could be adjusted towards, but you raise some valid points. We haven't rushed into a fix for this yet, but we are keeping an eye on it and may resolve it sooner than later.
