Suggestions: Diamond Gwiber available in 5.57 please

Please let the Diamond Gwiber available to buy with totems in 5.57 instead of 5.58 because too many people tend to leave the cross party because of being KOed too often and/or lack of performance in the Cloud Deck extreme. From my experience Players form cross parties for farming for the mount but each time they commence, they get KOed because of poor performance of clearing the trial and some cross world parties tend to leave after clear but left unhappy and impatient because of the mount did not drop. My guess it was like that as well in the High End extreme trials in the previous expansions. So that's why I request that the Diamond Gwiber should be available to buy in 5.57 instead of 5.58 and other future mounts that come from the final high end extreme trials in the future.
