The problem with fatecarver is the same HA-builds had: too much cleave. Single target damage could even be buffed. So instead of giving it 5% damage nerfs every now and then until it is not best in slot anymore it should get the sweeps/jabs treatment:
- The beam deals x Magical Damage to the closest enemy and x/2 Magical Damage to all other enemies
- Buff fatecarver by 5-10% to match the highest achievable single target DPS of other classes.
It will still be an incredible strong cleave setup, just not as trivializing as it is now. And Boss damage would be better. Prove me wrong!
