Example abilities like Blunt Arrow, Head Graze and jugugater. Do you think these abilities should have a potency attached to it, or should only have the effect?

I personally feel that the added potency turns these skills into somthing that you'd use off cooldown withouta thought, which imo breeds a bad habit when it comes to figuring out what can and can't be silenced, as well as the use of stun DRs on normal mobs.
