Mitigated/focused AoE passive circle(s)

Greetings. What I mean to request/propose essentially is a half-opposite of Amplify/Blast Radius and co. The said passives increase AoE and the bigger nodes add some damage too. I'm looking at Shock Nova when requesting a smaller AoE, mainly for its deadzone, while at it, allowing reduced AoE/more damage passives in would allow the introduction of further AoE skills that have odd deadzones - not necessarily a ring around yourself. Going into detail on that is beyond the scope of this thread though.

Also, from a support gem perspective, we have Increased Area of Effect with plain increased AoE and Concentrated Effect that takes away a fair bit of AoE and sets an overall damage multiplier. Mitigated AoE could add "More" damage too, or merely increased if More is too strong.


Balance opinions on it?

Feel free to hit me with a stick over the head if I'm reposting ideas.

I take it that there's 0 interest in ever seeing Shock Nova work in a more sensible manner?
