When it comes to raid progession (no matter what difficulty it is) we have two groups in a simplified version:
Group 1) People who have progressed.
Group 2) People who have not progressed yet.
Naturally Group 2 often would like some help from Group 1.
Now the questions are:
Should Group 1 feel obliged to help Group 2 even though it means they would have to spend time reprogressing the content? Or is it fair to want a quick reclear of content which they have already beaten?
Should people from Group 2 stop expecting help from Group 1 and instead make raid-teams with other people from Group 2 so they can progress together?
Edit: I realize now that this sounds like a guild scenario, but it’s not meant to be. Group 1 and Group 2 are representations of the player base in general. My bad.
