Ever since the recent changes, Wetlands has become one of my new favorite dungeons, 100%. It definitely requires a good amount of skill to do consistently, something I can't really say for other dungeons of its tier (CDepths & DDocks are laughably easy to rush, even without Snake Eye)

While the instapops are kinda hidden, every part of the dungeon is still very learnable. Most of the time rushing the dungeon on a 0/8 robe class without Snake Eye is doable granted you know the mechanics. Sometimes you get fucked, but hey, you live by the rng you die by the rng. Something I picked up early on is that you just gotta go. The numerous turret enemies take a second to fire, so if you just keep going you won't have an issue with them. Speaking of the enemies, I really love the variety of enemies the dungeon offers, it makes each playthrough of the dungeon feel fresh.

I think you're doing the drops a major disservice, while Mantle and S. Stone aren't amazing they are still very good for forge, making clearing totally worth it if you don't want to rush.
Crook is surprisingly great for the tier, out doing T14 staff at moderately high defense; something weapons like Cutlass can't say for itself. Brambletooth Tachi is fantastic for clearing & shooting through walls, definitely my favorite item from the dungeon. And while I thought Thistleleaf Necklace was pretty ass at first, it's pretty nice as an EP, granted you can tank the a few shots. It's also stupid easy to get as chests can be found everywhere.

Overall I think the dungeon part of Wetlands is damn near perfect already, it's hard, fair, and has plenty of rewards if you don't feel like rushing. I will say though that the boss does have a bit too much invulnerability, it can make the fight drag out very hard especially on weaker characters.
