After getting a Rad/Stone Brute up to veteran level 50+ and a Stone/Rad tank up to almost veteran level 20 it's obvious the tank is better at AFK farming. I thought Fury would make the difference but it didn't.. I was able to build in Musculature Alpha and added Hasten. Hasten might only work for 2 minutes but on a 5 minute farm that's +28% more recharge on average (14% for 10 minute farm). Biggest problem with this build is endurance and with end modification in Musculature Alpha, 3 Performance +END IO's, and conserve power things seem to work.
I'd like everyone to look over this build and let me know if you see anything that can be improved. Also if you have a build that you think is better please post it.
