The more woodsy folklore/ dryad type aesthetic is fine. It's been done many countless times by other games already and I personally like it. That's not what this is about.
Sylvari armor worked because it was at least semi realistic in how it covered you most often.
I can see the similarity with the original sin 2 version, but they ruin it by over exposing calves, thighs legs and mid sections. Can you spot the difference?
I sure can.
Really, there are so many ways they could have gone about capturing that woodsy/dryad aesthetic while still making the race appear both cool and different.
We could have even gotten this...
Instead we got this.
One seems familiar, but with just enough variance to appear distinct and flavorful.
The other looks as if it were made with such a focus on being different and unique, it never stopped to realize the look it achieved simply does not look good.
