They should have followed suit with the old raid and made it that maximum experience rates requires a group of individuals to at least promote more players to play together outside of 235 raid.
They should have made ryura max exp and gora slightly lower as I do agree that max exp within 1 minute is pretty absurd and eliminates the want and need to do the hardest level.
Kind of how players used to have to debate doing jura's requiem or mob deep on 221 for faster exp rates if you weren't pro enough
