Any recent racing videos?

I'm looking to see what the most viable builds would be for racing this seasons (technically i don't care about beating any times, I actually just want to level a couple alts as fast as possible).

Any videos detailing prophecy/ Essence league racing and suggestions for builds that lead into viable high tier mapping? My Slayer is currently 59 and I'm getting through A3 steadily, but I want to have the choice to play other characters as well.
