I'm just going to throw this out there.. but if memory serves me correctly

Shield Oath gives a 20% DR just by using it

Inner Beast will give a 20% DR ever so often whenever we have 5 stacks (with a smaller heal)

I see people talking about how they are changing to warrior because they will have this up at every burst of damage in the game

Wars will mitagate the same damage as if a paladin basically just stood there and did nothing.. and even less if he blocked it

I know Defiance should be compared to Shield Oath but for these ~Burst~ damage situations... Paladins will still be king imo
