It would be terrible design that would undermine the sense of accomplishment.
this. I multibox because i enjoy the challenge it brings. not the normal 5 x shaman iwin group ( allthough that in itself brings about its own difficultys) I am on about instancing at the correct level for my guys and with the normal gear. on a strange level i enjoy failing and wiping miserably, because i know when i do finally succeed i will be even more impressed withmyself and allthough its only me thats all i care about when playing a game.
on an exagerated level... if you could run 100 heroics and then be awarded with gear that had 10k stamina and a chance on hit/spellcast to replenish all health and drain it all from the enemy the game would be cakewalk and noone would enjoy it i dont think. I enjoy having to do heroics then onto 10 man then 25 man and seeing lots of people working together ( its me and 4 other boxers with a few pugs as some boxers 3/4 box) to actually acheive things.

I didnt mean to come across rude or as was nicely said " a dick " but i find it slightly annoying that while others are trying hard to acheive things you think that its your "right" to have the game opened up within a few months.
