Exactly. We are not pure yoyoing like you said, because there has been a lot of suggestions in this exact thread about how to move forward. Easy fix would be a best of both worlds, combining some of the old sfx and keeping the more impactful new sfx. But again that may only be me. But keep the current cart spenders as is and maybe revert the rest thus keeping the "impact" on the actual charged blade swings (gnashing combo, burst strike, fated) and at the same time allow the non cart related skills to keep the old blade sound ( 1-2-3, aoe 1-2, rough divide, blasting zone, lightning shot). I think you'd find most would be perfectly happy with something like or similar to this. It makes the people that liked the old sword sfx sounds happy, while at the same time keeping the players happy who thought the cart spenders originally were "not impactful enough" keeping them at current sfx.

Full revert is a thing too but I do understand there might be the small amount of people that maybe never played pre 5.01 GNB so they are used to/like the new sounds. And asking SE to create a 3rd set is abit too much I'll admit, which is why mixing both seems the most logical way to do it, to not only fix it finally and easily but to keep both sides happy.
