Recently Added level 50+ Training Spots?

I've been looking for a nice spot to grind at, but they're all just...decent.
I'm wondering if there's something really great for a level 50 Hunter.
I've heard a lot of new maps have been added, so I'm sure somebody has to know about a nice training spot.
All replies are appreciated.
Thank you.

Windraiders, C-2, V/Hoodoos and Golem's Castle come to mind.
