Rescue needs changed and/or removed

[Seraphor]

No.
Rescue is a very useful tool when used correctly and this isn't discounted by the fact that some people use it to troll by temporarily moving you slightly.
If they do it multiple times and it results in you dying, and you know for certain they weren't trying to help, feel free to report for harassment.

And in a not-so-pertinent-but-related tangent, a member of my FC recently passed away, he was the joker of the group and would regularly rescue us in our FC-only Trials runs, it was his thing. We just commemorated him in game by, among other things, doing an all-healer min ilvl dungeon run and Rescuing each other into certain death.
So outside of PUG runs where people are expected to play responsibly, it's actually quite a lot of fun to troll each other with it.
