Why are 1.0 lvl 50 dungeons are harder than ARR's

[Magis]

This is understandable because frankly, these 1.0 provides very unique mechanics that makes other dungeons looked kinda weaker, even Qarn & Stone Vigil (these also considered hard dungeons by some ppl) are easier.

Me and a FC mate were talking about this. Quarn has so many unique dungeon mechanics that make the whole instance so interesting. Yet it's a mid-tier dungeon that wasn't even part of the main story until it was shoehorned in for the extreme primals. Yet you look at the last dungeons and it's the same boring thing of "open this gate so you can't speed run it like back in 2.0.

Killing the heads on the pads or else they keep rezing.
The optional rooms you can open up that contain traps.
The final puzzle room to get extra loot.

Made the dungeon really interesting.
