The issue should never be "its old now, lets nerf it." because the challenge should stick around regardless otherwise players will never adapt and progress in their class, there's a reason why people don't get further in raid content and that becomes obsolete after a few months.


The "nerf" already exists, the weekly passby's of tome gear = better gear = better output from all classes. not to mention that the first catalyst for upgrading pieces is two turns into the second and final coil, in which lets be honest, if you're NOT raiding, why would you ever need these.
Raid gear is borderline pointless and it doesn't separate the raiders who do the harder content from the casual players who can get the equivelant output from their relic weapon + augmented gear, sure the stats won't be the best for their class, but because ilvl has such a huge stigma tied to it, they wont ever care, they'll see themselves as the best they can get and on par with other players of their class due to the cheer level of their gear.

the challenge should stay the same, echo shouldn't honestly be a thing and neither should the nerfs, let the players adapt to the "hard" content of the game and learn their roles effectively to LET THE PLAYER BASE GROW.. the only nerfs i could ever agree with is those which are mandatory such as advancements in story quests etc. the only thing i can even credit at the moment is the lockouts from t5,9 and primals. making players progress to progress.
