It would be pretty silly, but it is unfortunately the Dragonflight cycle repeating. DF S1 was harsh, requiring +20s for myth track vaults, and I think 17s for top tier crests. It was very frustrating for many players as a gulf formed between those doing 20s, and those not. Paired with stiff difficulty and some gross healer imbalances, it was a really bad time for me personally.
S2 was a total rowback on this, giving us mere 16s needed for myth track. Great season to collect mythic transmog, and I was happy about that because a couple of sets were particularly fantastic and I was able to grind out the crests with nought but time.
S3 and 4 went down the middle with +18s/+8s, were popular with players, and honestly should have been the target for gameplay and subjective difficulty for the future.
Unfortunately, as often happens in WoW, lessons are learned, and forgotten… and must be learned again. Idk if it’s due to different development teams or what, but we seem to have taken a step back in terms of accessible, fun content, and are again looking at a the same situation that had a lot of players drop from the game once before.
The funny thing is, it doesn’t matter what the actual difficulty of the “weekly” M+ key for myth track is, in absolute terms. What matters is that it stops getting fiddled around, because every time the difficulty spikes, a bunch of players wave goodbye for a few months. It’s dumb, and pointless, and silly, because the entire selling point of M+ is that it is already infinitely scaling. Getting your weekly 10 (or 8, or 6) done need not be a gruelling task. People who want challenge can go do 15s, 20s, 25s, whatever. But the common man, the mortal player, might just pause their sub if they can’t get anything done with their game time.
