ok, let me answer all the questions concrning wings...
yes, they fixed it from 5.0.4 so if you have pve helm, wings are orange and they flap 2 times and then they are holested back in, full animation
if you have pvp helm,like i do, wings are again purple(they were orange when it was broken) and they also flap 2 times and go back in,full animation
wings apprear when emote /roar happens OR when you jump, everytime you jump wings appear! that is cool, cause you jump anyway, while waiting for buffs or when running arround killing bosses on Hc or Normal....
i ve noticed locks get black wings now for challenge mode sets, which i think they ll work the SAME as these wings now. Only thing different now is we also get green fire shooting from shoulders and horns...and yes i agreee, the effect shout be a bit more stronger.
hope that clears everything out.
