The biggest draw for me is a mobile heal, like dodging bombs and landslide in titan, and casting adlo to top off the tank and shield for the incoming mountain buster without sacrificing mobility. Dropping instant raise is nice, but ideally, you shouldn't need it in the first place. Also, it's on a 60 second cooldown, which is pretty short, so don't be shy about using it unless you need to save it for incoming damage spikes.
