GW2 is often known as Fashion Wars 2, and it takes skill and a good eye to come up with individual and balanced looks for characters. Groups run fashion shows where players are encouraged to match certain themes or use certain pieces and it really brings people together, learning more about the arts of complementary colours and how to work on improving the appearance of your characters, how to realise an idea in your head. It can be considered a whole new game mode in itself, available to someone who's just stepped into the game all the way up to people who've played all of the story and want to try their hand at a different challenge. Individuals can - and do - spend many hours choosing pieces and dyes and tweaking things so it's all perfectly balanced... and now someone can just waltz over and steal the exact blueprint for their look without even talking to them?
It's one thing to take inspiration from others, but to straight up steal the look that took them a lot of work and effort to create? Not fair.
I'm not one of those experts in end-game fashion and not all of my chars have cool looks, but I enjoy looking at the creative and crazy fashion that people who are super invested in it come up with. I also enjoy coming up with backstories and personalities for my characters, and while my efforts certainly don't hold a candle to that of the masters, I'm not happy with the idea of even my poor attempts at a unique look could just be copied by someone else with no effort.
