You could do that before as well, it just wasn't worth using as a debuff.
I hope that rage eventually becomes a self cast ability only.
I can see how it thematically doesnt haveto be a self buff only, just like the good old ogre mages in WCII you could treat it like a "spell", but it feels like it makes more sense to work similarly to adrenaline in the scoundrel tree.
I'd like rage better if the flavor of it was more like a barbarian skill about going berserk yourself, rather than cast it like a magical condition on other targets.
I also think it will be easier to balance as a worthwile skill if it is self cast only.
