If I look at the content released for 5.1 as a pattern for future content (and it looks like 5.2 will be similar) then the future looks bleak for the more casual players:
  • 24 man raid: content you usuall run only once or twice a week for the coin and maybe the glamor piece of the week
  • Ex trial: a trial so overtuned (and designed that way) that's it very, very hard to PUG it. You only needed to look at the PF during the first few weeks to see how popular that was.
  • Ultimate: favoritism content for the minority of the minority of players
  • Crafting overhaul: that was actually needed long ago
  • Ishgard restauration: a 2 week one-trick pony that only is used for leveling crafters now
  • PvP: you only need to look at the queues to see how popular that content is
  • BLU stuff: another throw-away piece of content. I can gurantee you that in 4 weeks you will never find other players to complete your spell book unless you pester your friends.
