My thought is that if you've already raised multiple characters to max level, it's just unnecessarily punishing to have to do even more without the heirlooms.
For this expansion in particular you might run into problems because of the rep requirements for WQs, but that's fine IMO. Personally, I think the most important part is getting the alts up to 110 so you can get the AK research orders rolling. After that, going back to the various zones to get friendly rep is something that could be done when you feel like it. I've got 2 alts at 110 now, and even though I'm a little burnt on leveling atm, I'm considering bringing a 3rd up just so I can get his AK underway. I have no intention of playing him yet, but I'm handicapping myself by not getting those research orders going as soon as I can.
