Sorry, title should be: Group grinding.
It's in Pantheon right? Looked at the features/tenets doesnt really state clearly that it'll be in.
I hope so.. because I can't find anywhere that explicitly says so. Just like you said, social, interdependence... etc. But the thing is that could still only be in Dungeons/raids and events.. not actually group grinding.
So.. not sure. But then again it's open world.. so.. hmm.
They've very explicitly stated that the entirety of the game is designed to be strong socially and require high levels of dependence on other players for success. This is at all levels of gameplay, not just endgame. It has been explicitly stated that there will not be solo questlines/hubs and that soloing will likely be painfully inefficient compared to grouping, just like EQ.
Pretty sure it will be in:
