FOMO in FFXIV: How pervasive is it?

[Antrix]

so it's not as bad as other games, in fact, it is one of the best in terms of lack of fomo
I can list in one post all the forever missable stuff
1. legacy titles and the legacy tattoo: small coametic things you could only get during an event in 2012 assuming you played in the 1.0 version
2. the regalia mount and noctis lucis caelum outfit: will probably come back in a few years
3. pvp the feast outfits and mounts: will eventually become purchasable using pvp currency
4. pvp series 1, 2 and 3 rewards: also will eventually be purchasable with pvp currency
5. promotional mounts and emotes, merchandise only items such as matoya's hat: eventually purchasable via the square enix merch store but will cost you a pretty penny

I think that's it
every single other mount, minion, cosmetic outfit and emote is acquirable ingame or via the cash shop

Then it seems I've misunderstood the whole situation. I'll hope that indeed all that was available in the early PvP series will become accessible. Perhaps those were the points that concerned me the most. Thank you so much for clarifying the situation, I hope I'll stay in Eorzea for a long time, it's just so unusual here. I don't know what feelings I experience when I play FFXIV, but it seems to me that it's not a game at all. That is, it's not a game in the traditional sense of the word for me. This happened for the first time when I discovered Dark Souls. And here it's not about the genre, but about some not quite clear feeling, I don't even know how to describe it. FFXIV has a unique atmosphere, and that's what attracts me the most. And the only thing that initially repelled me from all this was fomo.
