It had a unique playstyle for a tank. I will start by writing what some of the artifact traits did.
Fiery Demise: Fiery Brand puts a second debuff on your target, increasing Fire damage you deal to the target by 40%.
Charred Warblades: You heal for 15% of all FIRE damage you deal. (Only on DH abilities)
Also adding Spirit Bomb Talent which makes you: Heal for %10 of all damage you deal to enemies with Frailty. (the debuff enemies get after being hit by spirit bomb.)
This, deal damage and get healed synergy is something I really miss about the spec.
