My experience with rescue as the "rescued" one is where healers have tried saving me with good intentions but ultimately failed because:

-I had a mental pathway on dodging something and the rescue screwed it up.

-You tried rescuing me to get me close to proximity heals. I don't have a problem with that but if you had read the situation carefully, we're in a no dmg phase because we're in some dps mechanic. Now I gotta run back to it.

-You rescued me from dmg...only for me to land exactly in another attack.

Now there have been instances where rescue has worked 100% as intended, that I won't deny but often time, I find it failing primarily because of the first reason I listed. Especially if, as a dps, I know full well the timing I'm going to dodge an attack. It sucks that I can't communicate this to the healer on the fly and I do appreciate their intent but perhaps rescue can be tweaked/replaced by something more effective.
