What would you replace Rescue with?

[Ilyrian]

So there you go. A variant of Rescue that grants a 1 sec invul. It would have to wait until 6.0 because now it would seriously be used to cheese some tank mechanics for sure. Devs would have to design content around it.

I like this.

They could bake it into the existing Rescue - it would circumvent the GCD and still have the movement effect as well.
You could make it uncastable on Tanks to avoid said cheesing - which you are quite right to point out.

I imagine it would still suffer the same fate as Benediction though without a complete overhaul of the programming.
