I actually used Rescue to great effect in Savage last tier, being able to pull a DPS lost in an eminent or revolutionary reign, so we survive the cleave made me feel special.

I've used it to great effect elsewhere sparingly... I don't really use it much, but when I do, it always pays off and feels awesome.

I know other people use it for trolling or do happy accidents due to the nature of how Rescue works.

I don't know what happened that caused such a reaction to make a thread about it. . . I mean, except for like pulling a Black Mage out of their precious leylines.
Which is really just a newer healer mistake. I know now to just trust a black mage knows what they are doing and give them a divine benison. If they die, they die.

A proper way to look at it is if DPS were trustworthy, rescue wouldn't need to exist.
So in reality, it's the DPS's fault for existing in a purgatory state of being a rogue element 50|50 in every encounter of either failing or doing the mechanic correctly. (This is a joke btw)
