Are my mitigation numbers off ?

A huge thing you are missing on the WAR end is Bloodbath, Bloodbath+Berskerk+maim, Equilibrium+Berserk, and other self healing abilites. Over the duration of a fight the amount of self healing WAR provides is a little obscene. If you look at mitigation as "HP that needs to be healed back" instead of "total damage reduced" the gap widens even more between WAR/DrK and PLD.

Additionally if you look at eHP as the same as mitigation (think Defince vs Shield Oath) you left out ToB+Convo which roughly translates to a 20 seconds of 18% mitigation.
