This reminds me of the ethereal season.
I’d prefer they make all good for push, as it is dull when there is only one clear choice.
For DH
Strafe ability: Make it work seamlessly with Rapid Fire and FoK legendaries and stick a 200% damage multiplier on player cast spenders.
Cluster Arrow: 3 beams instead of 1.
Vengeance: More frequent, allow on every Vengeance activation, but no more frequent than 8 seconds per cast.
For Crusader
Hammers: 6 Hammers boomerangs around the Crusader 60 degrees apart, 400% damage to Blessed Hammer.
Fists of the Heavens: 1 FotH per second, 300% damage to Fists.
Falling Sword Angels: these seem a bit problematic at the moment. Just make them powerful, but not exploitable.
