Make Merciful intervention (ground) targeting
This change will make Guardians a lot more mobile and have a flash skill much like the Elementalist’s Lightning Flash or the Mesmer’s Blink though on a longer cool down. That might not be what they want to give Guardians.
Though rather to whoever is lowest, they can just make it target ally(your 2nd option). It makes a lot more sense this way.
I really like this idea, even if it’s just the ability to target specific allies. It’s too unreliable and clunky right now imo
