This is not often taken that way though. What happens is the person is suddenly somewhere else and has to mentally reorient, and may likely have blown a cooldown in a now bad spot or have lost a few GCDs from their rotation and need to re-evaluate what still lines up.

And they may not know why even after whatever you saved them from hits - the camera shift and mental wtf will both possibly block them from learning...

Communication or just letting them eat the debuff a few times is better.
