Criterion Dungeons are great, but the entire system misses the mark.
After playing through the variant and criterion dungeons, I found the content to be very refreshing. Yes, I enjoyed the clue system and how everything leads to all the different endings in Variant. I liked the Criterion dungeon even more. I liked how I have to plan mitigation on fights, and dungeon bosses actually feel great and it was a fresh breath of air.
However, one thing I felt I had to say is this: I raid Savage. I have the luxury of being able to clear this content in a reasonable time, with extra gear that players who do not raid Savage may not have the opportunity to. These dungeons have the potential of teaching would-be end-game content players of how to approach raiding in general. However, the difficulty of the normal mode is set to basically be what it would be in Savage, and Savage is just the original but with a global enrage timer and harsher death penalties. This means that the people that would definitely benefit from having a 4-man endgame content the most (aka players who are trying to learn their role better and only having normal trials/raids). Moreover, I do also have a gear advantage because I cleared Savage, a fresh player would only have some pieces of tome gear, and new players to the system? Just fresh crafted!
In case I did not actually make myself clear, Criterion dungeons (normal that is, Savage is at the perfectly correct spot) are designed for the completely wrong reason. It should very firstly help players who are not comfortable with 8 man high-end content get into these high-end content (because a smaller group is just easier to manage), not a second piece of endgame content that high-end content players already can enjoy very well in. It also gives players who are hestitant on going into savage raiding (especially because fresh players today get shunned as they have no gear) a secondary way of progression, while also allowing players in general to also gear up alt classes to have fun and more importantly, help the newer/weaker players progress into high-end content.
Of course, I give YoshiP the benefit of the doubt. I don't think they had prepared an armor set for Criterion dungeons and it may not be in their first intention to do so, but it is very clear that the first iteration is VERY good. Just tone the normal difficulty down just a bit closer to EX since it is currently harder than EX, keep the Savage the same and give it replayable value by rewarding gear/glam on top of what is already provided.
