So you’re talking about a small group of people who get too much gear out of Delves and end up hitting M7 earlier than they should?
How often does that REALLY happen, I wonder?
Big enough to negatively impact a huge portion of the playerbase who does Delves primarily as their main content? I don’t think so.
I think some tweaks to the M+ system could solve some of these problems without yanking rewards away from delvers.
