So what happened to these.....

So i was wondering, what exactly happened to hex-tech crafting as a whole we saw it on the pbe i had a few goes a it with my time on it and i enjoyed the grinding aspect as it added something for me to do other than compete in ranked which i have managed to get to my goal this season. I have been looking for it but it seems as if there hasn't been so much as a peep, so what's up doc?
