Remove Rescue from the game.

[ZephyrMenodora]

Lastly but as I'll point out as your not against rescue that I do think its a good cooldown to help people know "yeah you should be not standing there" rather then simply healing a player. Rescue is a very good teaching tool which to your point of they've got to learn, this actually achieves in a effective way.

Getting damaged and getting a Vuln stack and even dying also accomplishes teaching someone that they shouldn't have been standing somewhere, more effective than rescue which may just disorient someone new to a duty.
