It is a difference between camps of people in mmos, and a big distinction I feel between those who treat mmos like oldschool mmos and those who treat mmo no different then offline games.
There is a load of stuff I have never done. I am still low reputation level 1 on all beast tribes. I have never done a hardmode dungeon. I have completed only the mainstory quest to unlock stuff so I have a ton of side quest left. I have over 80% of achievements still unachieved, I have not capped my chocobo. My crafts are not all leveled.I have never fished in XIV:ARR. But the real question is why would I take the time to do any of these. What does an achievement get me? What does a chocobo get me when I have a guild I play with? Why should I level a job that is based around the economy when Yoshida himself said it was his intent to kill off the economy? Why should I spend weeks doing dailys when the only reward is a vanity mount which gives me nothing more then my free chocobo? Why should I do a dungeon for Ilvl55-60gear when I am beating turn 5 and extreme and capping myth in 2days?
The issue is negated content and vanity content. Once content is meaningless I see no reason to even consider it valid which is how a huge segment of the game thinks as well. This is why WoW after so many expansions many people still say the game has a massive lack of content. It is why XIV has now and probably will always have a lack of content. 2.2 is negating crystal towers and probably extreme mode primals. 2.1 negated all hard mode dungeons(including the ones that were released in 2.1). The vanity system adds nothing to the game for me. I will not do old content for vanity purposes like Yoshida keeps saying people will do. Having a title "Honest Gillonaire" Next to my name will not make me do more leves to get it.
Many will disagree with me. But vanity, titles with no benefit, and meaningless trophies to me and many others are a 100% waste of time, that is not why I play mmos. I understand that a whole other camp will say well that is part of the game I am choosing to not do content. But to me and many other that is not content at all.
SE should tie content together to make it last for years, not purposely design it to be thrown away every 3 months.
