Tap leveling still work in WoW?

[Spook]

Does it still work? e.g. a level 70 runs unteamed with a level 5, level 5 taps a mob, level 70 blasts it, level 5 gets mad xp.

Any version of this still work?

This won't work, as the level five would only get the proportion of the damage that they did to the mob. For instance, if the mob was worth 20 points, and the level five hit it for one tenth of its hit points, the level five would only get two points, the rest would be wasted. There are two ways around this that still work.

1. Have the high level char be of the opposite faction. A level 70 Horde toon blasting a mob that a level 5 Alliance toon tapped, would result in full experience for the level five, as if he killed it completely by himself.

2. Have the level five paired with another toon of similar level, and have a high level toon with a pet be unpartied following along. One of the low level toons taps a mob, the pet finishes it off, the pair get full experience. This won't work with a solo character, needs to be at least a party of two. This works great for mult-boxers, but make sure that the hunter/warlock/death knight controlling the pet doesn't do any damage themselves. I flip up to a bare action bar to make sure.
