FFXIV ARR Disciples of the Land : have actions just like your Main Job Class.

ACTION : STEALTH
Each gathering class gets this skill at level 8. It is really a drastic change from 1.0 as with the use of this low-level skill you can walk right past level 50 monsters and below!

Also note you can use Return without coming out of stealth.

While under the effects of stealth you become transparent and suffer a ‘walk’ speed restriction.

So.. instead of people Teleporting is it possible what your seeing.. is RETURN being used. ?
