Hey all, this could be common knowledge i have no idea as i found it out today while playing my newly leveled 85 rogue.
It seems that the night elf racial Shadowmeld allows stealth abilitys such as Garrote, Ambush, Cheap shot etc. Now this can be beneficial in many ways from a extra pvp stun to that extra bleed on that boss! screenshot below for those who say it does not work notice how the "Requires Stealth" on garrote is no longer red even with Shadowmeld up. I consider this a exploit because the abilities require the ability stealth rather than shadowmeld, sorry if this is common knowledge!
