Ohhhh I get what OP’s saying! I thought they meant that its earned as in its cooldown state, but they mean how much prowess you need to actually pull it off(or even bother to in the first place) mid-battle.
Do you feel a great sense of accomplishment when you actually pull it off and aren’t booped, stunned, or blasted away mid-cast, and actually successfully bring your dead companion back to life?
If the answer is yes, then I guess you could say that you feel it was…“earned”… eheh, seewhatIdidthere?
But seriously, if thats the case then yes, I believe its earned if you can pull it off, since now I personally barely even bother to. Anyone who complains I just tell them to blame Blizzard and go about my heal/buffing duties.
