Long time farmer here (on both live and HC). On HC I have several common brute farm builds, and some scrapper and tank farmers.
I recently decided to make a Dom farmer, and went with what I remember people using back in the day a lot, fire/psi/fire. I just hit 50 today, and my build in mids looks amazing.
That said, I'm a bit shocked that everyone on here seems to be using plant doms. I did look at plant, and I just don't get it. How is it so strong or better than fire??
