My thoughts in no particular order:
This’ll make DHs required past a certain key level since chaos damage applies to all magic types and brand will increase all magic dmg regardless of type. Basically, VDH will continue to be the meta tank and stacking multiple havocs may even be possible.
30% haste is also a LOT. That’s a permanent bloodlust on trash. This will make interrupting priority casts significantly harder unless tuned (either haste % or cast times).
Could you please specify if Thorned will be a flat damage as implied by the referenced spell or will do % damage reflected based on the amount of damage done per attack?
I’m also paying keen attention to your specific wording, “retiring for Season 1”. Does this mean those retired affixes could return?
You’ll have seen by now, many people (including popular youtubers, MDI players, etc) asking how bolstering and sanguine were kept as they are by far the most hated affixes. I’m glad afflicted and incorporeal are gone specifically, while storming was more annoying than anything. Volcanic wasn’t really an issue as long as you had a melee dps in the group. Personally I would’ve swapped volcanic/storming and bolstering/sanguine (especially when they will interact with the new mechanics). Raging will still be a bit of an issue with the interactions of the new affixes but at least you can priority single target down mobs if necessary vs bolstering which affects all mobs.
Could you please elaborate on how many mobs per pack will be affected by the new affixes? Will be it be like the BFA affixes where it’s a single mob per pack or will it be more/all of them?
