Haurchefaunt and Ysayle trust idea

[Eloah]

I don't know why they took the name Trust from FFXI if they weren't planning to add NPCs like Haurchefant, they should've just expanded squadrons or given us nameless goons if they weren't going to expand it to all the fan favorites. Trust magic in FFXI is about summoning alter egos of people you've built strong bonds with to fight alongside you. It probably could've been explained in FFXIV as being similar to how the Exarch summoned the scions.

I think you're kinda answering your own question. If you read the description in the Trust system its says you are fighting with Avatars of trusted allies, or something to that effect. The system is quite similar to XI's but because of how XIV is, it functions a bit differently. Basically, they are only available in the dungeons not the overworld.

Estinien and Ysayle for the HW MSQ dungeons would make more sense, since they were with you for the journey. Haurchefaunt could be available for the Vault though since he was present there.

This mirrors what I was about to say. But I don't think Haurchefant would work as well seeing as how he would only be available for that one instance. Additionally, what would their jobs be? Retroactively making HW Alphinaud a Trust, would probably have him with the same job, maybe. Estinien would be a Dragoon, and Haurchefant would be a "knight" so Gladiator. But what about Ysayle, I mean what would fit her, "Primal" lol.
