So I figure I would share some info that I haven't seen here. Some of you are probably aware of it, the term "tapping", which got the first person to 70 in 28 hours (60-70 in 28 hours).

Basically heres how it works:
Person A = experience-or, the one who gets xp
Group B = The killers. Theres a nice explanation of the level limitations here (http://www.wowwiki.com/Formulas:Mob_XP)

A attacks mob, B kills it. A just has to do 1 point of damage to get credit for the kill!

I leveled a friend from 43 to 47, pre 2.3, full-rested in 2 hours. Not bad considering it was myself, and him, no boxing

Anyhow, if you have a 70 and are boxing and/or racing to make the fastest level'd char of all time, why not try this? It has a couple assumptions though, which can limit some people from doing this.
#1) You will need to make two high level sets of twinks -- 49 and 59, and optionally 69.
#2) You have the desire to power level other characters of yours, or of your friends.
#3) You enjoy burst damage -- your alt chars should be chosen based on maximizing burst potential for the bracket.

1-44 the instance grind. Should take less than a day played to get to 44.


Recommended team: warlock (get's DC at 42, very powerful 49 twink)
Then at 42, go to Feralas and start tapping, using the level 49 twink-team. You can choose to do the quests available, but it might be counter-productive, especially if you find yourself running back and forth a lot. Ogres, hippos, yetis, elites.. all good choices. Aim for 30 minutes per level.


Recommended team: hunter (best overall sustainable dps)
Once you hit 50, you're off to Felwood to grind T-maw rep with the level 59 twink-team. Theres a good chance of blue drops, as well as a Gutripper if you're lucky. By 55 you're ready for Winterspring; I'd go straight for the whelps (elite) for some serious xp and some decent loot.

At 58-60 you're off to outlands. Using a 69 twink will let you start at 58 (going for level 60-62 mobs). By the time you hit 62, you can use any and all level 70's to be your kill team.

MISC.

It can be helpful to have a healer/res bot in your kill team to eliminate downtime.
I've had best results if you run your kill squad as a mage (food/water), warlock (no down-time), hunter (pets!)
Google: "mage aoe grind spots" to find good locations to grind away at.

Any thoughts, comments, questions, rebuttles appreciated.
