Until dps and tanks stop dying to the very obvious instant death mechanic because they would rather dps til death instead of actually dodging the easy to dodge mechanic, then rescue stays. On the flip side though, I dislike rescue when playing as a tank because there is always that one healer who ends up using it on me because I didn't move to the spot they moved to, despite still being safe from the instant death, and end up dead because the healer decided I needed to be rescued to their spot and end up getting caught in the instant death when I would have lived if the healer had just not did anything. I don't fret about it though, at the end of the day, this is just a game and it is a waste of energy to be legit angry over something like that. I've never once had a healer who intentionally used rescue to troll, both as a dps and tank. Usually it's always just being used because the healer doesn't trust me as a tank to survive, or uses it to try and save me as a dps from something I either didn't know about or was zoning out and not paying enough attention at the moment.
