I'll try to find a small interview snippet, but yeah, Aura meta is still a thing. It's not as bad as Wraith Pact since that was just a singular item that was built every match without fail. But now we have Shivas / Guardian Greaves / Pipe / Crimson that all contribute to some Aura effect.

Mirana being in the meta is solely due to her second facet. It's such an insane damage amp.
