For egg legendary, element advantage is reversed.

Because of fortitude II, which all the egg legendary will have,

Their element advantage is reversed.


The order of eggs, I believe, will be


Ice--- fire---- water---- electric----earth---plant.


And ice will beats fire, fire beats water and rock, water beats electric
Electric beats earth, earth beats plant and water,
and plant beat ice and fire

that the new legendary all have fortitude II, it still doesnt mean that the elemental advantage is reversed. they may receive lower dmg from the element they're weak against, but they still do low dmg against that monster.

if fort 2 reduces att by 50% (pure hypothetical)

fenrir vs cerebus

fenrir with 120 power ice attack would deal (120 base x 1.5 stab x 0.5 elemental disadvantage) 90 power
cerebus with 120 power fire attack would deal (120 base x 1.5 stab x 2 elemental advantage x 0.5 fort 2) 180 power

if fort 2 reduces att by 66.7% (also pure hypothetical)

cerebus with 120 power fire attack would deal (120 base x 1.5 stab x 2 elemental advantage x 0.33 fort 2) 120 power

interesting thought though

Absolutely right , only misscalculation can come is from buff/debuff,dodge etc.
