I've looked it up and it seems to be exactly the same DPS ?, did I do something wrong? Here's the output: https://www.raidbots.com/simbot/report/hX2Zyxbt5cGpKk6oH5PLW4
If DPS is the same, I'll just stick with my 405, as I don't have to rely on an extra mechanic from demonic transformation.
Using the calculator, the new traits are arguably worse but I also read that a +15 ilvl is usually worth it. I'm personally not a fan of the new traits at all and I feel like the lower ilvl item has far better traits that seem to outweigh the ilvl difference. The full list of options on this piece:
Chaotic Transformation vs Seething power
Revolving Blades vs Secrets of the Deep
Elemental whirl vs Azerite Globules
Burning Soul vs Bulwark of the Masses
Should I use the new one or the old one?
