I know that the stats were nerfed some, but what is happening is this. The "total" crit it is giving is the actual "crit" listed on the essence. Under Physical Crit, it should also be applying crit received from the increase in dex and it is not. Dex should help ap, crit and dodge, it helps the others but not the crit.
Can you please check on this and verify?
(I have done this with my spreadsheet and kept screenshots of before and after adding new essences so maybe I'm missing something but it doesn't appear accurate)
