One of the weirdest complaints I've seen over the years (and especially throughout the Shadowlands Alpha/Beta cycle) is regarding how content without any in-game reward is simply not worth doing. While everyone is going to differ on what they do enjoy & what they don't enjoy, to me, the end result is simple: If you need a tangible reward to consider doing something worthwhile, then it isn't something you enjoy.
A lot of people seem to be happy with Shadowlands & its laid back approach to what is "required" for player power progression, but others are seemingly less enthusiastic, and I don't really get it. If you don't think M+ is worth doing past unlocking your weekly M+ vault rewards then you can go do something else you enjoy instead, right?
I enjoy M+ so I'll continue to play them anyway, just like I'm sure many people continue to PvP despite the rewards being absolute trash historically.
What's wrong with that? With less being tied to player power, we're looking at an expansion where doing the stuff you consider fun is looking to be easier than ever, which is why I'm going to be pet battling, alt leveling, & achievement hunting fairly early on this time around
No feeling like you might be left behind because you didn't do your BfA list of chores - just log on & do the stuff you enjoy!
I get that it's an RPG and there needs to be player progression, but that's still there 100% with the covenant story development, gear coming in a slower but steadier pace, etc.
