Seriously. That fight is what you guys should be aiming to reach with all your Ultimate encounters. I don't mind if the various random encounters along the way aren't as challenging or interesting, but all the big time battles should be like that. Interesting and unique fight gimmicks and a challenge for some of the top players. That fight is definitely my new favorite encounter in the game.
I like the direction of Ultimate Wildwoods overall though. Monster variety definitely makes the place feel much more fresh than Ultimate FSC. Also, I liked the new Snarby battle. In a group you aren't as engaged but for a solo player the fight definitely felt well-paced and fun.
Was not impressed with most of the new content, but Ultimate Wildwoods, and especially that first arena, were incredible.
