Honestly, feel free to go into detail, the more support the better. Personally I don't want to develop stockhome syndrome with these sounds so I'm straying from this job atm and trying DRK again I guess. I was too used to and ready with the original sounds that this change is just a big no-go for me.
I did mention rough divide but no one acknowledged it either, it feels like its kinda nice that it isn't so squeaky but similarly just doesn't really give as much oomph as the other tank dashes(animation wise it's a bit lackluster too for it being one of Squall's most iconic skills). Of course everyone agrees with what you said about the keen edge combo entirely. Rough Divide is known for being the skill originally that Squall would use after reznokuken that had him slash upwards and "divide" the enemy in half with a ton of rocks and earth being sent with it. In Dissidia, this instead was changed to a more simplified "dash" with the sword bursting with light and him rushing to the target and slashing into them. We ended up with the latter version as a means to have a tank gap closer that also fits the "skill name" as a reference to the gunblade user. It never really had a gunshot sound or overall trigger sound, it's kinda just a dash.... It still sounds as wimpy as it used to imo but eh, not much they can do I guess with it.

^ 20 seconds in is the Dissidia version of Rough Divide. Although Revolver Drive right after that, not being an original skill, looks and sounds pretty badass... prolly wouldn't fit for the gunbreaker though since they don't just use revolver styled gunblades like him. If anything, I feel we should've gotten a animation and sound more matching what Thancred does in the CGI of Shadowbringers. Something more akin to a long range dash with a twirl during the dash rather than a weird flip at the end with a squeaky impact at the end. Something more akin to the implication of you dashing almost "through" the target, piercing, but also powerful.
In any case, I'll live with rough divide how it is either way, the main combo and our overly done continuation combo is my biggest issue right now.. And them toning down blasting zone felt completely unnecessary.
But yeah, old sounds had more detail in them imo with as you said, the trigger pulls and mechanisms of the gunblade working + explosions/slashes in equal form.
