Except, Sudden Death isn't a minimal DPS gain and you're not getting nearly as much rage from the Devastates as you think. Sudden Death is 1-1.5k dps above Heavy Repercussions, and you lose minimal rage.
Sudden Death dps increase math:
Note: All numbers taken from
these logs.
Procs: 2.5 per minute
SD Damage: 58k per execute
Total Damage: 145k per minute (58*2.5) [SD DMG * Procs]
Heavy Repercussions:
Shield Slams per minute: ~10
Shield Block %: ~50% (this is playing very defensively)
Shield Slams buffed by Shield Block: 5 (would take very in-depth sims to faithfully recreate this, but it should correspond to Shield Block uptime*Shield Slams)
Shield Slam Damage: 35k
Total Damage: 52.5k per minute (35*5*.3) [SS DMG * #SSbuffed * Heavy Repercussions buff]
Damage Difference: 92.5k per minute (1.5k DPS)
More in-depth Sudden Death Math:
The above math is overly simplistic and doesn't account for some of the points that you mentioned earlier. So, this math will try and touch on the rage gain/Heroic Strike usage.
Each Devastate you do is worth 12.25 rage (Note: My crit levels not yours. You would get less value). Math below:
[Base Rage of Shield Slam + (% Chance of Sword and Board Proc)(Rage value of Sword and Board proc) + (% Crit)(Rage Value of Enraged)][% Chance of Sword and Board Proc] -> [20 + (.5 * 5) + (.2 * 10)][.5] -> 30.6 rage
So, you lose 30.6 rage per minute using Sudden Death. It's important to note that you only see this rage benefit by using Shield Slam when Sword and Board procs. Thus you end up spending two GCDs to generate this rage, instead of the one GCD used on Sudden Death. One of your arguments against SD is that it requires GCDs, but when played optimally it doesn't interfere with Shield Slam timing.
If you used the rage generated on a Heroic Strike: 9k damage
If you used the rage generated on a Shield Barrier: 50k absorb
On a typical boss fight Sudden Death is worth 750k damage. The rage you generated by not using Shield Barrier is worth 350k healing or ~100k damage if you used it on Heroic Strike. That is an abysmally poor tradeoff.
Spreading "opinions" that lead other players to play sup-optimally/poorly is not a good thing. If you're not a main tank, and you're not sure that your "opinion" is correct don't suggest it to other players.
Sudden Death, when played properly, is universally better than a Heavy Repercussions build. I would only suggest using Heavy Repercussions if you're struggling to manage Sudden Death procs. As mentioned in my earlier posts, this is not the case for Amby.
