So far Barbariccia and Hydaelyn are the only Endwalker Trials i would consider at the level of Extreme.

The others have just been a very basic dance, with 1, maybe 2 mechanics that actually matter, and once you hit that point, the fights just fall over without much effort.

Comparing that to Shadowbringers where the trials were a lot more punishing for messing up, it feels as if they have dumbed down extremes to try and get more people to try them.
(Which is not a bad thing, but it does make it incredibly boring for people that enjoyed the content previously.)

A lot of the new trials have mechanics that are:
A) Predictable and able to be cheesed.
B) Able to just be Dorito'd (Marker on 1 person, follow them).
C) Ignored because the mechanic doesn't punish you enough to actually think about doing it properly.

A lot of the issues just boils down to the trials being scaled back enough to the point where you over gear the content before it releases.
(Look at Rubicante, it released as a 610ilvl duty, when most players that do the content would have already had a majority of 630ilvl pieces of gear, or equivalent upgraded crafted gear at 620.)
