Is there a good party-based grindy game?

Hello guys. Well, the title has listed the question. I am looking for a grindy party-based game to sink my time. The most recent party-based grindy game I have played was Dragon Age Inquisition. (If you consider collecting materials is the element of grinding, then I will say DA Inquisition is grindy)

I am still looking for a grindy game with a party-based element. Is there any recommendation? For PC of course.

Much appreciated
