Хочу добавить, что начинает это все дело работать только с 80 уровня и выше.
A note for Night Elf Rogues : for the first 50 levels I wasn't able to land an opener (Ambush, Cheap Shot, Garrote) from Shadowmeld, all skills requiring stealth are marked red.
I'm not 100% sure until I reach level 85, but my assumption is that after they re-enabled this combo in 4.2 they reverted only the code for the last skill level of the various openers, in fact I cheched with a friend of mine and he can do that with his 85 rogue.
Will confirm this info as soon as I reach the cap.
EDIT: Confirmed, it starts working only from level 80
