First off, I am totally cheating by engaging the raid dummy with fully stacked Bone Shield and RP but that is just to ensure I stay alive long enough to merit uploading the video.
The main points here are:
- Spectral Deflection just chews through your Bone Shield charges, potentially making a Haste build that focuses on Marrowrend only viable (depending on SD tuning anyway). It also significantly lowers RP generation over the normal rotation that actually uses Heart Strike.
- The legendary bracers are as broken as expected by allowing 25 RP Death Strikes (though you do lose Ossuary's effect at some point due to how quickly you lose charges).
- Death Strike healed for nearly 100% of my HP - though that was during Vampiric Blood so it's not base HP, but still. I mouse over the healing breakdown at the end, look at the bottom right and pause as necessary to see the min/max/avg heals.
- Vampiric Blood had about a 30 sec CD via Red Thirst there and that is without the other legendary that affect its CD (which, admittedly only works off of Heart Strike, so it wouldn't have helped in this particular scenario).
- Check out how little effect all the Leech effects had combined compared to the other healing.
