The 3rd PoE race by 
Here is the trailer for the new league that is starting soon:
I think my first character will be Essence Drain Trickster. Besides the smooth progression(cast everything, wait till the spells spread and kill basically everyone, move on), it could also come handy this league if we consider the damaging effect of the darkness.
It won't be that smooth though. I died with that character in the first race but let's hope this time it will be different! :D
Going down the mines is really tempting because of the rewards. I'm not sure if I'll instantly try it with my first character but at some point, to advance quickly, I think I'll have to give it a try.

Good luck and have fun!
