An interesting point has been brought up on the official forums: Why should it matter if someone wants to solo when most of the content is instanced? That is, why should a player group? Here's what Sporkfire had to say:
It will be possible for players to solo to some extent, but its not the optimal method of advancement. One of the main things to keep in mind is that group-oriented content just tends to be more compelling, more fun and have greater entertainment value (i.e. we entertain two or more people on one quest). In a perfect world, we'd support both playstyles equally, but we have to make the decision at some point on where to focus our development activity.
That post can be found here. Each playstyle is rewarding in different ways and a healthy mixture of both does prolong the enjoyment of a game. What do you think? Are you a solo grinder, or a groupie? Let us know in our forums!.
