Upon updating today, I couldn't help but notice that the Vengeful Gladiator's Felweave Cowl that I use for transmogrification had suddently become red. Asked other guildies to check that for me, and the result was the same... it was red, like the Malefic set, and not blue like the Vengeful set.
Also worth mentioning, it is the only piece that was changed - the rest of the sets look the same. So I wondered, "What the heck did these guys touch, to break this item!". I wanted to see if it was only the helm, or if the wings were changed as well... but they didn't come out. For a moment, I thought that they had even removed the wing effect!
And then I jumped. Much to my surprise, the wings suddenly popped... then dissapeared. Tried jumping again, and there were the wings again! So... yes, apparently they thought it'd be "fun" if the Wings deployed when you jumped, as if one were Count Dracula. An arguable idea at best... but worse still, the effect isn't quite convincing, as wings just appear and disappear, instead of the usual "fading" effect when coming out and back in.
Madness, I tell you!
