Because time-lines of different types of content are not all “now” anymore, that opens the ability to have the raid instance also being available as open world map at some point after we completed the raids.
The question was if this was already the plan, and if not, this is a suggestion.
So what I mean is that a few months after a raid has come available and has been completed by many players, that map could next to being a raid, also be an open-world map that in the time-line is just after you completed the raid.
Most of the design for the map is done anyway, so you could add some events, or just leave it empty, but explorable with the story hints. It would be a nice way to expand the open world area.
