Besides the fact it's a recolor (depending on which set) it's very much different. at least enough to tell which one is from panda and legion.Also i don't know what server you play on but on mine the challenge mode set are very popular. I see about two to three players a on a normal day with this set (and a lot with the weapons as well) while they are hard to get they are some of the most used sets in game and a recolor (actually a reskin with the parts taken off) is nice. Mostly for how pretty they are and different (like the druid set) Please stop looking at something as a bad thing and enjoy the rare recolor you will have of it. after all people will be sick of this set once they get used left and right.
