Hello
I am very confused on this subject, I have written to support but it turned out not to be too helpful thought they tried 🙂
I am level 38 and part of Elyos, I was informed by support that in order to see where I can do essence tapping I had to turn it on in the map, so I was told to open map with M which I did, and then look at the left and click the check box, there is no check box for essence tapping on the left side of the map here is what I see when I open it up and all these have a check box I can check or uncheck:
