I'm starting out with Primevil and going the cookie cutter route. Once I max it out, I'll level up Battlerage and Witchcraft to give me maxed out Dark Runner and Shadowblade as well. Shadowblade is my favorite build but I just didn't want to primary level the same thing again that I did in Alpha.
Here's the two builds for Primevil. Some variation between them.
What is everyone else building?
