Why cant we have better quality and new models on cloaks and dresses?

So its been 15 years, the graphics have been improved by a lot, I see no reason why cant we have a better quality on cloak and dresses.I mean, why are the dresses and skirts always so long, hiding boots, glitching etc? Why cant we have better models of dresses, shorter, ending just before boots (like Khadgar's ingame model), cloak around leggings (Anduins model) and overall better graphics and detailed dresses?So about cloaks, I feel they are too static, too boring not animated properly. I think cloaks are cool, they can be even scarves, or hiding shoulders.What you guys think?
