The only thing I know is u need at least 1 Crusader in your party. I'm farming Golden Flenses with my Condem Crusaders with the only difference of replacing SoJ with CoE. F&R is too painful to keep up permAC so I went with RoRG + CoE which is far better than SoJ. Had the idea to add 1 Roland's crusader with Shield Bash. Holy shit! I'm spamming 8b crits on elites depending if I have AC up. RG fight went down from a minute to a few seconds. It's CRAZY single target damage. RG for GR37 literally goes down under 10 secs. The charge sucks but if u get used to moving to your targets instead of aiming at them, its fairly easy to deal with. The main problem with it is survivability since it doesnt have permaAC and no APD but at least for low GR40s is perfect.
