This isn't actually how it works. Experience gained is deteremined by damage done (when ungrouped) hence the warlock who got world first 80 with his pocket healer.
I -think- that Athene is using a scaled up version of the plan - with like 5-10 pocket healers.
Don't quote me, but that is my guess.
Still not sure why Blizzard didnt implemented XP gain scaling to damage done to mob, which would stop this kind of powerleveling. Simply you did X% dmg of his health pool = you gain X% of his total XP. From the reports and video it seems that this model isnt linear at all and allows significant XP chunks just for tagging part, regardless dmg done.
Or am i wrong on something ?
Calling him a no-lifer is stupid.
The people who grind to 85 in a few hours are actually those that spend the least time leveling.
But I think that people who rush to 85 that way are actually those that have the least fun playing, or leveling.
What does it matter if you hit 85 on Tuesday or on Sunday?
I'm only 82 but I really enjoyed Mount Hyjal. It doesn't matter what level I am cause I'll do all of the zones anyway.
And I'm sorry but I fail to see the achievement in such a thing. Grinding mobs for 6 hours and having a bunch of people help you doesn't really impress me. Jesus. Sounds so boring.
