Forced Grouping is not a term being used by VRI, Group focused or Group orientated are what they say...Solo'ing will not be discouraged but as they design the world, encounters and classes they are focusing on interdependence between the players...IF players find ways to solo (Fear Kiting, Root Rot etc) through emergent game play they will not look to nerf that unless it is truly game breaking (Bards soloing entire zones). The thinking is that the group focus on content will help build a stronger community, where name and reputation means something.
