It's hard to rate Oribos/Maw on that scale. Oribos is a fine capital city, but it's clearly another player hub "city". I was hoping for a proper city like Boralus/Zandalar again.
Maw is meh. It's already kind of dull. It'd prefer if the content was weekly not daily. There's none of the great "challenge" promised and it's pretty annoying to fill up the bar to tier 5 everyday. Today I decided not to bother with it beyond the two dailies and only push when I'm in the mood. It's basically another Mechagon/Timeless Isle. Waste of time hunting for rares that die in seconds to fill some bar or finish some quest. I think a lot of the challenge is lost quickly once you get gear. I think day 1 it was somewhat difficult, but now that I'm in the 180s for ilvl it is easy.
I love my forest though. I would burn down the world to protect my Night Fae.
