Yes! Exactly. Duh. So you have a baller self-heal and some good on-demand mitigation at the cost of your defensive stance being like, 1% weaker.

no because defiance doesn't heal your HP after you switch to it, you need to rely on healer to heal those HP gained, meanwhile grit and SHO are damage mitigation so the effect are instant
and just because WAR has good mitigation does not change the fact that they have 3 new useless skills that will give WAR next to nothing to help them with new content,and the fact that you still think that is fair again shows that you don't know what you're talking about
