Next Criterion Dungeons - Where do you want them to be?
My first pick would personally be Garlmald. I really want something to help us flesh out the area a bit more, I'm disappointed with the lack of content in Garlmald, and some good old lore treading in the region would be welcome.
Second pick would be somewhere new to the New World. Actually, I hope this comes first before anything else. While I'm excited for Vanadiel, I'm personally more of the thinking that new raids should expand upon the expansion locales while they have the time to shine, and since this doesn't seem like it is happening, I really hope that we get a Criterion dungeon in the New World, so that we have a proper exploration/lore bomb in one of its locations. I feel like Criterion would really help explore something like down the road. Especially post base story.
Third pick would be Ala Mhigo, because like Garlmald, it also feels forgotten and useless. I think we could really use a lore bomb there too. Especially if it has anything to do with the glowing ark that is just sitting there.
My last pick would be Gridania, and specifically in the home of the Duskwight. The game acts like they don't exist, which I don't particularly like. A proper duskwight exploration drop would be wonderful! It has been a while since we had anything to do with them. Come to think of it, Criterion might also be a good way to explore racial origins. Perhaps the same could be done for the Hellsguard which are barely ever mentioned.
