I think having a solo aspect to MMORPGs is important, but shouldn't overshadow the multiplayer aspect to it.

It's good to just log and do activities alone to relax one day, and then fully indulge in organized PF high end duties on the other. However, about the multiplayer aspect, there's something quite funny about XIV's encounters. While you usually do those in a multiplayer scope, there are very little interactions needed.

Let's say the 2min meta, which some people die by the hill that it's important because it promotes "group play". When it was the last time you were in a group that coordinated the 2min burst in a different way? The structure of most of the content itself just encourages you to do your opener and just press everything on cooldown afterwards, as the burst windows will naturally align. There's no actual planning needed salvo for very specific and uncommon situations.
