Yeah, all I tried was the default Bo Staff.
According to the dev streams this update is supposed to come with a lot of game-wide performance optimizations as well, not just limited to this new landscape feature.
The new nunchucks and their endless stance combos are so god damned much fun. Seriously recommended for ridiculous shit-eating-grin amazingness.
The rapiers are also super deadly, and easy to combo. And gunblades.
If you're looking for interesting new melee weapons to try out.
The bow and arrow is super fun to use, but I wasn't feeling the melee stuff. Nunchucks sound fun though.
