They're mostly fine. Most of the issue is pugs not knowing how to do the dungeons, use their tools effectively, or thinking ilvl/rio = skill. If you just slam invite on anyone with a high ilvl then get destroyed by the key, realize the top groups are doing it at 5-7 levels higher than that with maybe 5-10 more ilvl, and they did these keys in the first 2 weeks with 390-395 gear.
There are a few things that need to be changed, but almost everything is fine right now. An example is last boss RLP in mechanic frequency, certain overlaps, and the fire DoT. A lot of people on lower keys fail this dungeon and think other things are overtuned, but outside of edge cases like Flamegullet on fort + raging without a soothe, which is completely skippable, nothing else is.
