I would just like to know why it is possible to replay storylines. It would have been easy to write this in and explain why it is possible.
We know that there are psijics who possess secret knowledge and secrets. A new artifact could be added for them—an ancient scroll—and a small storyline could be developed around it, after which it would become clear that thanks to this scroll and a couple of magical spells from the Order of Psijics, it was possible to see the past and relive that life again. Or connect it with the lines of fate of Itelia and with different universes (not directly with Itelia so as not to intersect with the main plot). In general, a lore artifact through which you could replay the story quests of different DLC zones. Of course, there is the argument “create another character and replay it” - but this is a bad argument and not a good one. There is a character on which all the storylines have been completed, and I don't really want to create another character for this.
Wouldn't it be a useful feature to be able to replay that storyline again on your main character, either alone or with someone in a group?
P.S - I'm talking about the main storylines in a given location, the first and main storyline with Molag Bal and others. Not side quests.
