Interesting. I should think about a "/cast [@player] Infernal Strike" binding for my DH tank.
The number of times I've ended up facing away after mistargeting one...
ETA: Even though my Immo talent got nerfed, they changed the worst thing about the spec:
Felblade is now usable against targets in melee range even if the Demon Hunter is rooted.
Super great change for someone who plays by muscle memory! I wait until Felblade happens to start Shearing again, so I've often lost 2-3 GCDs wondering if I'm lagging out. In case you never experienced it, because Felblade has a charge component, you were unable to use it when rooted. Even if your target was in your grill.
