Overall, I think Retribution is in a good place and I enjoy the current design. However, there are a couple of areas where I think the gameplay could be improved without fundamentally changing the spec.
The first is Execution Sentence and Wake of Ashes. I think these abilities could be merged into a single button. Right now they are almost always used together, so having them separated doesn’t create much meaningful decision-making. Instead, it mostly adds another keybind and an extra GCD. Merging them would make the rotation feel smoother while also making the priority target and/or funnel gameplay more intuitive.
My second point is Tempest of the Lightbringer. The 20-yard range feels unnecessarily restrictive, especially in dungeons like Nexus-Point Xenas, where positioning changes constantly. Missing the correct angle and pulling a pack of ennemies or having enemies move slightly can easily cause the ability to lose a lot of value, which feels frustrating rather than skillful. I think removing its range or making the targeting a bit more forgiving would improve the gameplay without making the spec overpowered.
Finally, while I like the current version of Retribution, I personally preferred the previous 30-second cooldown cycle. Having your major abilities line up every 30 seconds created a more consistent rhythm throughout a dungeon and made the spec feel more fluid. The current cooldown timings sometimes leave the rotation feeling less cohesive, especially between burst windows.
Overall, I don’t think Retribution needs a redesign. I just think a few targeted quality-of-life improvements could make an already fun spec feel even better.
