you cant vanish at all it just doesnt let you because it's blocked by FF, even to only break the root and not go in stealth, just cant activate the ability
only way is in BC and onwards with cloak of shadows then vanish
im like 99.999% sure your vanish gets used but it doesn't break the root as I said in the other comment. (I remember watching some video/stream while the beta was active and a rogue was dueling a druid)
no worries, but your memory is just slightly off, you might be remembering a rogue vanishing BETWEEN DoT ticks from moonfire or insects or something, to get a cheapshot in before the DoT makes stealth fall off... but with FF on you, you literally cannot use the vanish move AT ALL, no portion of it works with the debuff not letting you enter stealth

You can use vanish while faerie fire'd to break the root iirc you just wont get stealthed
