If death in the game had meaningful consequences, then i might be inclined to agree with you. As is, it just doesnt. Report if they were really obnoxious(black list if needed), and move on.

And FYI, you can dodge their rescue if you REALLY want to. Your ability to prevent knockback/other forced movements works on rescue. That requires you to see the sneak attack coming and predict that you will be the target(or reflexively hit your skill any time someone runs out of a same spot), but it does totally work. You could also run in the opposite direction they went to the far edge of the safe zone - for some attacks this can put you outside rescue range.
