Get Heroic T15 2 set. Worth the loss of stats solely for the bonus to Enraged Regen it provides.
Basically gives us a Vengeance empowered Enraged Regen without needing Vengeance. Back in ToT when I was still soloing 25 Heroic LK for my Invincible that thing would regularly heal me for 350k+ with 40-60 rage.(2) Set: Each attack you dodge while Savage Defense is active increases the healing from your next Frenzied Regeneration within 10 sec by 10%, stacking up to 10 times.
