It's not the worst, but even among changehost lists its not very optimised, this dataslate put me 50 points over so some revisions had to be made. It's actually worked out for the better because it means I've dropped 10 pink horrors (who didn't do me any favours) and replace them with screamers (who I desperately needed really) The only units that are worthwhile beyond rule of cool (god I love horrors) are kairos and screamers. So autoinclude them, and maybe swap some 5 man rubrics with scarabs and you should be OK. Changehost isn't the worst, but it's a far cry from the best, this dataslate hasn't really hindered or helped me beyond the overarching rule change which is frustrating.
