To put it simply, DF Ret is looking too ST focused again and the modern game doesn’t usually favor specs that are pure ST, especially when they’re not even the best at that small niche. Looking at Frost DK for example, nearly every part of their kit cleaves: Breath of Sindragosa, Howling Blast, Glacial Advance, Chillstreak, Remoreseless Winter, Obliterate with the new DnD talent, etc.
Ret on the other hand is very ST focused. In the current patch, tanks can outdamage a Ret with no cds which is not great. I think Final Reckoning should be used as a model in DF and most of the pure ST talents should be changed to incorporate some AoE.
Blade of Justice
As an ability that’s heavily modified by talents, it would be nice to have an option to cleave with it. My personal preference would be to allow Exorcism to modify/replace BoJ and DoT cleave in consecrate.
Execution Sentence
This ability is now smack in the middle of our tree, emphasizing it’s importance. However, it doesn’t provide any benefits in multi-target situations. This could be rectified by allowing it to damage all enemies in range when it explodes.
Also changing Executioner’s Will to pulse AoE damage while ExS is active would be nice. Another idea would be debuffing enemies with each pulse so they take some additional damage from our abilities, sort of like a weaker mass Judgment.
Templar’s Vindication
It would be great if this applied to Divine Storm as well, like the Echo of the Highlord trait did in the Legion artifact.
Final Verdict
All of the other capstones provide some benefit for both ST and AoE, except this one. I would propose combining it with Tempest of the Lightbringer. If it’s too powerful, we could drop the HoW interaction or move it to a different talent.
Judgment
Timely Judgment’s 1s CDR talent might be numerically okay, but feels like a pretty bad pick. It’d be nice if Judgment’s cooldown was set to an appropriate number (~8s) to begin with and a slightly buffed Boundless Judgment (50% chance for Judgment to chain) put in its place.
Light’s Decree / Sanctified Wrath
Please consider giving the AoE component back somewhere. Liadrin’s Fury might be a good candidate since it’s a very bad capstone right now.
