In every MMO I see a section of people that insist on asking for a 'solo player' mode. I feel they do not get what an MMO is about.
That said, I can understand where they come from in FFXIV and ESO - games that historically were mostly solo game and now also have 2 and 1 MMO each.
But this is still an MMO... and it reminds me of how I see this even in a game like Overwatch - where there is a regularly occurring set of posts asking for a PvE mode... for a 'first person shooter' game...
This is, at it's heart, a team player activity. It is not meant to be played solo. If you really want a solo game, an MMO is not the right choice for you.
I am on the flip side of this... the only game I ever really played before finding MMOs in 2005 was Civilization. I cannot sit through a solo game...
Take your game format for what it is - and figure out what you like - before you spend your money. There is a pile of old games from the 90s in my house, because it took me several purchases to realize I could not do solo games... I'd play for a few hours and get bored...
If you already know you don't like group games... PLEASE try to figure that out before you buy one... Take it as advice from someone who wasted a lot of money when they were younger before they figured out it wasn't worth it... No matter how cool the title looks... figure out that you don't like the format BEFORE you buy. That's why I haven't bought a single player game since 1999. Not even new versions of Civilization past maybe 2001 (only because it was advertising multiplayer modes, but they didn't turn out so good back on dialup).
You bought FFXIV... it isn't for you. That's one failed purchase - $50 or less. Took me over $500 before I stopped buying solo games. Don't do it again if you don't like group play. Move on to FFV - I wish I could join you there, but that's a solo game. Not for me, it's for you.
