Not denying that it's there- as I said that key range is where people are the worst meta slaves. My point is more that many of them are being idiots who don't see further than raider.io's guides. Maybe things will turn around in a month when people realize that tons of rerollers can't play the game for shit no matter what meta class they use, who knows, I'm not being optimistic but stranger things have happened. I know that in my keys, I've actually had more success avoiding hunters and mages now because it means I actually get players who know their class and don't get free invites, or high IO people who know their shit but are insufferable about it.
One thing I will say is that dungeons feel harder this expansion compared to BFA and especially Legion, and especially on Tyrannical where even on +12 some bosses feel harder than half the Mythic bosses I progressed on (hi, Sanguine Depths and Necrotic Wake) where one misstep means a pretty much guaranteed wipe. That probably causes at least some of the attitude I bemoan.
