So, is that a dagger? (In the new concept art.)

[Shioban]

I don't think anyone is saying flat out "no"

I am.

They do not outsource their concept art and just say "go wild"

I never ONCE mentioned them out-sourcing any art, Kazuya Takahashi and Akihiko Yoshida both WORK(ed) for Square Enix and did a fair bit of concept art for them. Not ONCE did I say they were out-sourcing. I challenged the fact that they might do a pick'n'mix on what looks best rather than "Is this best in slot", but obviously this is a moot point with the upcoming glamour system.

More importantly, bang goes the theory and here's my proof. You even said it yourself;

They have never drawn a wildly inaccurate player character using a weapon that obviously does not exist, in a manner that is obviously not possible, wearing equipment that is obviously not meant for the class.

So unless you can explain why that thief is wearing Vanya Breeches of Healing and a pair of acolyte boots....

Glamours are class restricted. War/Magic cannot glamour each others armour/weapons. (IE: War cannot wear Magic. Magic cannot wear War)

Sorry but it's not a thief, or a bard, or a gladiator.
It appears to be a Conjurer and or Thaumaturge.

Here you go;




"BUT THE POSE OF THE WEAPON"

This is concept art, no-one in this image is holding their weapon the same as they do in-game, so it's perfectly acceptable to change it up.




Also, it's a female Miqo'te. As due to the skirt, and female version of the boots, and the feminine shape. And the breasts.
