Casting Aether Attunement cleaving arcane missiles is one of the most enjoyable things to me about playing an arcane mage. It feels amazing when it procs. However, one of my issues with playing an arcane mage is I feel like my AoE is not as consistent as other specs, particularly frost. Having to burn through three clearcasting procs to get my missile to cleave doesn’t feel great to me. We’re already reliant on procs to cast the spell in the first place.
My suggested change would be for the Aether Attunement talent to make all of your arcane missile casts cleave, rather than every few casts. Along with this change, the bonus damage could be reduced/removed, to make it balanced. It’s location on the talent tree could also be moved, perhaps swapped with High Voltage to make it an AoE-centric capstone talent, which I think would be a more appropriate capstone than HV.
I believe this change would make arcane AoE much more consistent and enjoyable to play, while also making Aether Attunement a more impactful choice as a talent.
