Kill Command also needs to be like its TBC/Cata version or similar (would rather it get a unique SoD change).
Hunters also need a rune overhaul so hopefully we get it in P4 but at this point I doubt it.
Some runes like Cobra Strikes or Invigoration have never been used and never will in their current state.
I’ve proposed changes to improve hunter runes and their pets before (click here), should you be interested.
