I am not a number wizard like keyboardninja or have KItru's experiance with a geared 50 in every AC.
I still preach the balance approach of stacking some HP with defenses. I can understand I'risa's point of the extra HP, the light armour has several disatvantages. Sure we can mitigate more on firebrand than any other tank, but incinerate still hurts. And Kitru's idea boils down to being healed less with I'risa's being able to not need healing longer. Both tanks understand the healer has other people to heal besides them. This is the stumbling block in the two schools of shadow thought. This is my statement I hope kephas doesn't crit on me or im dead at full health with 27k hp in denova NM
