Ridorana Lighthouse:

We were on the last boss; I'm tanking. Yaz winds up a Rake, so I ready a Vengeance. Next thing I know, I'm being sucked across the arena into the middle of the group by a White Mage.... the boss follows. Rake goes off and kills 6 people. The White Mage did this to me twice during the fight, each time killing several people. When the raid ended, he was so proud of how many people he managed to kill that he was bragging in Alliance Chat.

Second boss of Ghimlyt Dark:

The boss went underground and started burning the side of the mountain. Myself and a Black Mage ran to one side, the Astrologian and the Ninja ran to the other. Neither group was in danger of being hit by the long-column AoE. Right before the AoE went off, the Astrologian used Rescue on me, pulling me directly into the line of fire. Thankfully, I'm a tank and it didn't come close to killing me... but the troll game was real.

Alpha 1:

Cyclone phase. I pulled the boss to the corner, then moved to the cyclone to prepare for the Damning Edict/Knockback combination. The healer ran to the corner and used Rescue, pulling me to it, then ran to safety. The boss turned to me and cast Damning Edict. I popped Inner Release when I noticed I was being Rescued (knockback prevention, because the cyclone hadn't gone off yet). Shortly after, the cyclone went off, knocking the entire group into Damning Edict. Thankfully, there was enough time for most of us to run out of it. Still, that was a dicey situation.

As you can see, my experience with Rescue is lackluster at best, and these are just three of my most "memorable" encounters with it. My biggest issue with it is that it gives one player the control to move other players. While this doesn't necessarily sound like a terrible thing, people can easily abuse it for their own amusement -- or just as bad, inexperienced players can use it because they don't know any better. I'm not saying Rescue is bad and needs to go... but it definitely has the potential to be a headache. WoW had this same ability called Leap of Faith that was met with so much backlash, they actually created an item that would prevent Leap of Faith from having an effect. It's probably not a bad idea to implement something like this as well. I'm not a fan of the ability, personally. If I could opt out of it having an effect on me, that'd be swell.
