Because XIV has made housing THE game at this point. CBU:III has developed that unhealthy relationship with our need to be social with items and a virtual building we can design. They then FOMO it so that we have no real ability to re-gain that true end-game unless we stay subbed.
How are we not allowed to be upset at that fact? It's fine that other people can basically let that content go, but anyone that's actually played long enough know that it's not just something you let go of.
It'd be like if The Sims deleted your house every time you stopped playing, then when you wanted to play again after a few months it made you do a lottery to get it back. It's the same basic idea. Especially when we know there isn't much other content to keep us occupied otherwise, it makes The Sims part of XIV basically the only thing we can do.
If we eventually get proper instanced housing, something like WildStar (Bless their heart), then it wouldn't be this way and we could all live comfortably knowing we can unsub when there's no combat content.
We gain nothing for praising FOMO, we all lose as players because of it. Let us be upset at that, so we can grow and be a better game. Please.
