I know nothing about this, but it's strange that the base(white) value on stock mangos equals the base + bonus values on elysium.
Elys: 120 + 180 || Stock mangos: (120 + 180) + 180
Elys: 175 + 120 || Stock mangos: (175 + 120) + 120
Maybe coincidence, but it can also be that on stock mangos you got the bonus twice(or you get half the values on elys)
