Pretty much worthless. As poster above said it'll only be good when stacked with more save tp, which could very well lead to a closed circle of dds not using that atma anymore since they don't know if they'll be in pt with the cor and the cor won't be giving a full support if not everyone is using it. Outside of vw is just horrible. I hope you missed Fighter's/Rogue's cause we're going back to lv 75 rolls.
Chaos/Rogue's with warriors and monks (and ninjas I guess), and then Chaos/Fighter's with everyone else. At least, that's what my brain is coming up with initially.
I can live with it. I don't like it, but I can accept some roll variety.
I think the biggest downside is I've got to sink a metric f*ckton of cruor into atmacites again instead of spending it on making gil. >:(
