I'll just go -4 mog +4 Grim. Grim can always shoot himself in the head to deal with Ichorid. I have bolted Nactles FTW, and compared to that, he's a lot better.
The Pridemage 2 for 1 comes up infrequently, so he is usually just as good. The change hurts your affinity match up, anything else? I'm sure their are moments with jitte or something. He's still savage, even nerfed.
