OK, so I've flown a few laps around the new zone on PTR.
The entrance is admittedly pretty cool, but the zone overall is boring as hell.
It's like they combined the fiery Djarddin areas of the above (the least appealing biome) with a bunch of dark rocks, muted colours, etc. Not even the crystals do anything for the place, as they're all the same darkish green colour.
Major disappointment.
It's the kind of place where you go in, suffer through your dailies for 20 minutes, then fly out with a sigh of relief.
Paladin set looks super badass though.
