I want to take my squaddies outside like chocobos
Basically, the title: I'd like to be able to toot a horn or something and have a specified member of my squadron come out and fight alongside me, basically as a chocobo replacement while leveling. Chocobos and bardings are cool and all, but I'd rather take my glammed dudes out in the world with me.
In WoW's garrisons (which squadrons seemed to have a fair amount of inspiration from), a certain subset of the people who you could send on missions were also designated as "bodyguards", and would follow you around the field and fight with you. FF14 eventually implemented squadron dungeons, which is similar, but part of the fun of having glam options is showing em off to other people, and it'd be cool to be able to take them out for new-expansion leveling (though obviously not for shadowbringers, but maybe the next one) instead of just in solo dungeons.
A potentially weird part about it would be people who have the same squaddie out meeting in a zone and seeing their squaddie's clone, but WoW solved that by just calling other bodyguards by generic names when you saw them, so in XIV you could essentially do the same thing and call them Hyur Marauder/Lalafell Thaumaturge/etc, and it wouldn't be all that weird.
I don't particularly like doing squad dungeons vs normal dungeons, so it'd be a nice way to keep the squad content relevant instead of having them just standing in the barracks all day.
