For me specifically Rescue has done more harm than good. I have only ever had it used on me a hand full of times in my FFXIV career, but it has been unnecessary every time. I have either been "rescued" straight through or into a mechanic I would have otherwise avoided, or "rescued" too early from a mechanic I would have got out of anyway if they had just waited a second longer. I know they are trying to do the right thing (maybe) but with the way server ticks work, and the possibility for visual and input lag, it just doesn't work the way it's suppose to.

There should be a toggle in the character settings that just says "Rescue? On/Off", and if you turn it off Rescue doesn't work on you.
