ofc Im aware of everything you wrote, that’s why i suggested to give max 10m+ ivll quality locked behind some grind in open world, blizzard could make any solo content and some challenges through events etc that would show a bit how to play too,
in general blizzard should make more rewarding SOLO content that would learn how to use toolkit.
I don’t think repetitive scenario would work cuz its not fun at all, but making something like brawler’s guild could be fun.
Maybe they could hide +10 grps etc for everyone that are below certain m+ ilvl, same for +15 etc with range.
I think it would really help with a lot m+ key issues cuz lets say anyone who’d have enough m+ rating to start getting +10 keys ( and find grps above 10) would rather know mechanics and strat of dungeons
(keystone master which is acc wide, whould make you see all grps on alts)
