If 6 hunters were possible, wouldn't the table have 6 sides to sit on, not 4? It clearly shows one hunter occupying each side making a quadrilateral formation.

Also, it was already confirmed that it's still only 4 hunters per quest, the lore about such a rule seems to make the rule eternal and never-changing.
