They can’t do that unless they fix the snapshotting bug.
If it goes live as it is, you’ll probably start to see LoD Mammoth Hydras abusing it. LoD Mammoth Hydra normally runs 60-80% fire (bracers, amulet, Swampies, sometimes Cindercoat), with the snapshotting bug you could switch to cold, and pretty easily snapshot 200+% fire (around a 40 enemy pull) with Black Hole: Absolute Zero. In a dream rift, a 250+% snapshot (a 60+ enemy pull) isn’t out of the question.
As it stands right now, fire/arcane/lightning wizard builds can pretty easily leverage SoJ + Black Hole: Absolute Zero into a ~2x damage bonus (80% elemental vs. ~250% elemental, or 40% elemental vs. 200% elemental), snapshotted for a rift floor.
A LoD Mammoth Hydra build that normally runs 80% fire with Cindercoat and Unity could swap to 80% cold (bracers, amulet, Swampies, lose Cindercoat, gain SoJ) + Aquila’s + SoJ, have equivalent toughness (losing Unity but gaining Aquila), and deal as much as 2x damage. It’d effectively be less than that since you’d be losing out on the Spellsteal buff, but the Spellsteal buff is temporary and you could snapshot in an an SoJ Absolute Zero buff into fire and keep it for a rift floor. Then you just need to fish for a 90-100% progression Festering and get a massive snapshot. And never potion again or die after that.
If it gets buffed to give double elemental bonus, you’d be able to snapshot in a much higher buff. So all of a sudden you’d be talking an 80% bonus vs. a 500% snapshotted bonus, so you’d be leveraging a potential snapshotted 3x damage bonus from SoJ for any non-cold wizard builds.
Potion snapshotting is an obnoxious mechanic though. I’d hate to see that come back again.
I think they have to fix the bug before they can consider buffing the SoJ effect.
