best place to find builds?

I've been following cRPG Bro's YouTube channel, and it works, but I'm curious if there are others I should look at. I wouldn't mind some that are just text write-ups, so I don't have to watch a 45-minute video.

Lastly, what characters did you use? I'm only at level 15, and some seem much more effective than others, but I'm probably not using them correctly.
