I just got him in a free roll. Should i use him in my raiding team? I have SK, Rockno, Ghoul, Pd, Aries and Val.
If you don't have any other heroes, than you can put out Val, and than put GF there. Other option is SK. GF is very strong, and his proc also remove buffs from opponents, which s good. With good talent like SS8 he is still very dangerous.
I'm a big fan of grim! He was my first OP hero and I still use him in some areas. His skill is awesome! He deals big damage to enemies in front and removes their buff, restores his own hp, and he has built in 8/8 berserk! Depending on your other heroes, I would level him up and play around with him. He could replace Val, Aries, or SK. I prefer him over rockno in dungeons.
