It sort of is, but that's not intrinsically a bad thing, nor does it need to lead to the game lacking in social contact.
I've always preferred to play online games 'alongside' other people. Or to be more specific, we do the same content, helping each other, but are not really reliant on their presence to complete it. PSO was the first online game I played, and it really set the bar for what an online game should be in my eyes, and that game literally had a single-player mode.

As far as I'm concerned, the biggest issues, as I've stated before are guilds, and the type of group content being offered. The first causes a problem due to the tendency of those in guilds to become insular and distant from the community as a whole. As for the latter, when you have a linear-progression style of content with all of the rewards at the end, and necessitate that everyone is reliant on everyone else, it leads to a situation where other players are just regarded as necessary tools for people to get what they want; any time spent socializing or chatting is time not spent expediting the journey to the reward.

As far as the game being soloable goes, the only major thing I see with that which might conflict with being social is that you're not allowed to do the story/class duties while in a party. Other than that though, it's not an issue in itself.

To me, at least, its not a good situation if the type of 'socialization' a game fosters is merely talking about strategies to succeed in group content, nor is it good if people are social only because the game has forced them to group to do something they really don't enjoy doing.
Socializing should be something laid back that happens amongst the entirety of the community as you play; not something super-serious, nor something you have to try and force people into.
