I love shadowmeld but due to my add on, it justs tell me when I'm fighting someone n they shadowmeld. I'm not saying its not OP , but I think racials are based on player's playstyle, plus I never agree with Bis list just due the fact I feel most people should have several gear sets.
But I will agree in MOP you will see less rogues and if you do , you'll see more nightelfs and worgens rogues due to racials.
