Taunt only temporarily makes you the target and doesn't actually add any/very much enmity at all, and it lasts for only a few seconds. You taking 1-2 swings isn't going to get your party killed and if you get hit you always have Second Wind, and, as was brought up, a possible Haymaker stun is awesome. Of course, certain NMs are dangerous to do this with but if you're smart about it it won't be an issue.

This! ^ Taunt only gives temporary hate for 5 seconds then fades
