The Epoch guys seem to have a much better handle on content and level design compared to the Turtle devs. I've leveled multiple characters and raided on Turtle, and while it has huge amount of custom content, its all noticeably amateurish and feels like a lazily-tossed together mod.
Pic related is a shot I took straight from the new Gnome starting area that the content guys threw together in like a week while the server shit itself during the initial launch. Obviously it's all using repurposed assets, but the sense of framing and "lighting" is surprisingly good. The Gnome starting area in general sold me really hard and made me really hard.
