- Normalization of carnavalesque armor
This is an overlooked but real damage, so ingrained we don't see it anymore. Warcraft 3 had those ridiculous designs, but you saw them from above and were usually too busy clicking around like a madman to care too much about the "let's mix every race and watnot in fantasy together and bind them in Looney Tunes cartoon" style.
Now it is fuckin everywhere, from Warhammer to the Guardian of the Galaxy bad guy, and even when designs are not a direct rip from Wow's we got used to see flashy childish color everywhere.
Maybe it's part of the appeal. It looks like a toy world, nothing is serious or plausible, you are there to enjoy yourself and not think about the harsh socio-economico realities of fantasy war. Whatever.
