We have armor class agnostic sets now - cosmetics usable by any class that can be functional.
Why can I wear a murloc onesie and that be fine on my warrior, but the line is drawn at a pair of cloth pants? Or why can I wear the Stormwind Guard set on my Mage but changing some of my pieces to the leather catalogue is a step too far?
I know a long time ago the team said they wanted it to be obvious what the player is just by looking at them, but come on… as soon as you hover over someone you get a tooltip telling you their level, class, spec, and race. Let people make their characters look the way they want.
(I’m mad because I really like the motorcycle mounts coming in 11.0.5 but the only good biker transmog is for cloth, come one let me be a cool plate wearing hell yeah brother watch out for the clibbins gobbless kinda guy on my warrior pls)
