Delete rescue from the game.

Does the Arms Length and Surecast have an animation too? If so, we may have to pause our rotation if we think someone is going to troll Rescue. It's not a perfect solution either if you actually have to almost stop what you are doing out of fear for this. As for uses for Arms Length / Surecast use in other things, not much I can name for normal difficulty encounters. Pretty much just Barbarissa Trial comes to mind to make it much much easier.

Arm's Length and Surecast are purposefully on the oGCD.

There are several instances you can use it. Praetorium has a KB for instance.
