Are my mitigation numbers off ?

[Reynhart]

Defiance doesn't reduce damage, only increases health and healing on self.

Technically yes, but calculations have been made to prove that all tanks starts at the same "state" when using their Tank stance.
And if we do a step by step fight with real HP and real damage, both eHP and mitigation will affect the outcome.
Did we already mention that WAR also has the most eHP increase with its skills ?

Thordan Ex's (mostly) physical damage called. It says "Hello".

Oh, nice. Long time I had news from him.
How do his children do ? You know, Lightning Storm, Ancient Quaka, Sacred Cross, Holiest Of Holy...
