Tman

Confirmed . While in combat, if you use VANISH , it will only remove the movement impairing effects and enter and improved stealth mode but it will not trigger Stealth*the aura will not apply / the action bar will will not change thus making impossible for the rogue to reopen with a cheap shot , garrote or resap the target , nor Overkill even if you have points in this talent*which triggers only when you use Stealth*
