The writing is serviceable and steadily declining; if you think this is peak writing please read a book. There's no need to make a fuss over people not caring for it, they're really not missing out on much.
On the other hand I can't imagine why anyone only interested in raids would choose this game. There's not much, it's locked behind hours and hours of dialogue + lockouts and the combat system is ok but gets stale quickly. There's gotta be something catered more towards them. Same for PvP fans.
