Delete rescue from the game.

Some main problems are that Rescue can be used by trolls too and GoatofWar is probably asking for a counter to that. Even with the bottom considerations, there may still be a few trolls who would need a kick for being a nuisance. Usually we can't do that at the start of the dungeon, so an immunity effect could be used as a last resort.

We could stop the Titan deaths by requiring the healer to be on ground. We can mitigate Suzaku's middle hole by making Rescue lift the target in the air to actually get the ally to your position. The delay could be removed or greatly minimized so it can actually rescue the target more often.

Anything that follows the player can also be used by trolls. When Euphrosyne was released, there was an alliance that was formed of many FFXIV content creators that ran it blind together and made a contest out of who died the least, which inversely led to players doing things like trying to catch other players in the AoE tankbusters, or running circle AoEs into one another. They were laughing and having a blast because it was one large premade group, but anyone can do that at any time. If someone wants to troll, there are countless ways they can do it. Removing Rescue will not fix that issue. It is not a problem that you can fix. That is the reality of MMOs.
