I'd love for them to pursue more open-world aspects. Perhaps they could even make a large (Dragon's Dogma large, or somewhere near there) area with lots of mini-bosses and various enemies and locations scattered about, with plenty to do for both solo players and groups alike.
But that's simply a fantasy. The reality is, they're more focused on linear-esque events and DLC. Which is cool and all, as it is their game, but the way they're pricing and implementing everything makes it...well, less than satisfying for some after awhile.
