Powerleveling as a necromancer

[tranceminus]

I've got a 60 necro, and was curious about leveling a friend with it. He's got a 36 monk. I googled a bit and saw that if you dot a mob, have the other person hit it, then feign before it dies, he will get all the exp even if your dot finishes it off.

This thread was from 2012 though, is this still true?

What about pet damage, if pet kills it while I'm feigned, does the other person still get the exp?

Finally, anyone have any experience doing this, and got some suggestions for good places to go? I was thinking around his level, maybe doing CT or Splitpaw. Would appreciate any other ideas, thanks!
