It's debatable as to whether it's intrusive in the first place, since unlike World of Warcraft's version of the ability Rescue has limitations in place to prevent it being abused freely.

You can choose to only party with healers that you trust if you're so concerned about the ability being misused even with the limitations in mind. I'd also question you on one point - how often, in all honesty, do you see the ability being misused? I'm not saying it doesn't happen but I do roulettes on a near daily basis and I have not seen the ability be misused.

I have, however, seen numerous uses of the ability preventing a death or even stopping an entire party from wiping. I've seen it used beneficially in both PvP and PvE content.
