It's being developed by the same team as the mobile game, so I imagine their level of p2w would be similar.
I'm not sure if Nutaku even controls the cost of in-game items. They probably only broker gold purchases, and the rest is up to the devs. Makes sense, since they don't need to worry about a specific game tanking as long as overall revenue is 👌.
All those recent DMM games were handled by Superhippo. If anything you can blame them for being shitheads.
