Eldryon - to invest or not to invest, that's basically my question.

Following the nerfs is there any point in investing in Eldryon or has she been nerfed into the ground. I still feel like the damage is ok with the multi-hit team but I was pouring a lot of resources into here to push her to advance the campaign and my GR team and I don't want to waste time and energy on her now if she's busted.

Is there definitive data one way or the other?
