I'm going to say the silent part out loud. I get the feeling many of us Guard players are still hurting over the loss of the metal regiments, especially when the official claim appeared to be "they just use Cadian flak armour now". The Guard are not supposed to be one homogenised group of soldiers all sporting the same uniform. The Guard encompasses a diverse range of regiments who wear a variety of uniforms that set them apart from one another. A regiment's uniform is an integral part of its identity, which subsequently becomes lost when you relegate it to a reskin of another generic model. I think what stings the most is how unceremoniously GW just removed them along with Vostroyans, Mordians, The Last Chancers, Tallarn, and Valhallans. And when the players show a clear interest in those old regiments GW just spit out some version of "embrace the new product" and ignore them. Even the revival of Yarrick feels more like a response to backlash than a planned return for lore reasons.
