I'm very worried that based on the complete silence from the dev and community teams regarding the ongoing issue, that they're just waiting for the negative talk surrounding the GNB sound effect changes to die down so that they can sweep it under the rug and pretend like there's no more problems.
The fact of the matter is, regardless of how people feel about the adjustment to the cartridge ability sound effects being good or bad, almost everyone agrees that the Solid Barrel combo and Demon Slaughter combo feel awful without their slashing sounds, and without the actual trigger pull and fire sound effect on Solid Barrel itself. Looking back, we can see that there was a vocal minority dissatisfied with the cartridge combo and had voiced their want for something a little more substantial, but as far as I've been able to see, NO ONE asked for SFX changes to their standard combo abilities. At the very least, if nothing else, I think most of us would agree that this change should be reverted.
Devs, community team, regardless of if you're evaluating feedback on this and considering a change, or your stance is these changes are here to stay, please at least let know where you stand so that we can make decisions about if we're going to continue playing Gunbreaker or not before we get too invested into the patch cycle with a job that our enjoyment of has been seriously hampered by this change. I'd personally go back to Warrior if not, but if a change is coming at some point, I'll continue on in faith that they'll do right by us and give us something higher quality.
