It only makes the OLD models have a helm like in those pictures, a velious helm.
There are no velious textures for the new models, or different helm look. The new models simply copy some of the velious helm looks by default. For example the troll and ogre are similar with ANY plate helm, while the dwarf is not.
So the quest is still the same, but is only of benefit if you want people with the old models AND velious textures on to see you that way. This is kind of the sad thing about now having THREE different cosmetic possibilities per character (old model, old model with velious textures on, Luclin model) The way players view each other is fragmented, I might look cool to me but look like a doofus to you. You might look great in your default viewing way, but look goofy to me.
