So I took a crack at this, I've never tried either set, but I think I'm happy with the result. Shadow Meld will only be down for about 10 seconds, near perma-hasten, resists could better but I'm not too worried about it. Should also have a somewhat decent attack chain. I'm open to any thoughts/critiques/suggestions. Thanks!
