Why in gods name do you people think everyone play this game the same way as you. You want to know the nice thing about FF14 compared to WoW? I can get a nice set of gear, see the content and not have to deal with hardcore raiders or pvp'rs.
Not everyone is playing FF14 to savage raid or do Ultimates. Why does it matter to you that people are doing Glamour in FF14 as their end game? Are they happy? I would take FF14's end game gearing system over ANY other MMO's end game gearing any day of the week.
If you want to know why these people are "idiots" then look in the mirror. FF14 actively discourages joining FC's and forming really guilds because of this horrible static system this MMO has from a period of time when it was dying. You would NEVER talk to a guildmate the way I see people talk in FF14 in Savage. You would be kicked for toxicity and held accountable by a guild leader.
