My game experience isn't dependent on a friends group beyond the game. I'm in an FC and I enjoy their company but it's almost a separate thing to the game itself, and if they all abandoned the game then it wouldn't affect my experience of the game much.

Most of my actual gameplay (outside of the "basically a single-player RPG" story aspect) is spent either in roulettes, hopping into party finder groups for content I feel like running, or playing dress-up dolls with my WoL collection.
