I've used Rescue more times in ShB already than the entirety of SB.

My usual cases of Rescue in ShB so far:
1.Final boss of 71 dungeon double just over half room cleaves you get hit by 1 i will rescue you to safe side(you already lost dps due to being knocked up)
2.all bosses of 75 dungeon each and every one i've had to rescue people to safety sometimes wish it had a shorter cd >_>, Last boss more if i see you don't prevent knockback.
3.Titania ex vines just to allow the melee to keep as much uptime as possible

Then you have the myriad of people who run away with stack markers or worse run from me when i have it (your above level 70 you should know the marker by now), the people who just don't move for anything and the people who troll with mechanics for their own amusement.

Has Rescue been misused by people, oh yea, always going to be bad apples at points, i still remember you hlr who rescued me as i was about to technical finish to the far edge of platform where no else was (and then proceeded to not use a single dps spell was icing on that sundae) but doesn't mean the skill needs to be removed or have an opt in system else every skill that interacts with a party member should.
