Just spit balling here, I have played this game steady since launch on console, I took a few week break and played destiny 2. After experiencing the ability to save the raid groups progress through their end game raid, I feel like that particular tool would benefit a vast majority of players, new and long standing. Being able to pick apart a raid a little piece at a time gives a bit more Confidence to newer players they will eventually get through it, rather than grinding it out for many hours only to lose your progress. Also allowing an experienced raid lead the ability to halt progress knowing they can come back to it another time. many of the trials guilds that I have been in set a limit of two hours on any given raid that the group is progressing through. after that two hour mark people tend to lose focus get frustrated etc. being able to escape that environment and come back another day fresh and focused one may pick up on a mistake they were making a little easier. this mechanic already exists with maelstrom saving your progress after each stage, making it far more conceivable to complete.
