I've been mulling over what I should do, so I figured I'd bring my dilemma to the forum. First a little context:

I play a tank, and I'm an avid raider. I'm hoping to get started on Naxx with my guild quickly. We've set an a cutoff at 4 weeks for everyone to have their toon levelled to 80 and ready to start hitting Naxx, although there's a few of us that have set personal goals of 2 weeks. It should be relatively easy to meet that goal dual boxing my raid geared warrior and my new pally, but I'm wondering if I can reasonably meet it while 5 boxing. Additionally, I remember what things were like for me as a tank in BC. I would log in, and would instantly receive 3 or 4 requests to hit an instance. With that in mind, I'm concerned that I won't reasonably have a window of time to level my alts for a couple months.

Right now I'm leaning toward just front loading my effort and 5 boxing to 80. At least then I'll be able to solo instance when I'm not swamped with requests to tank.

What do you guys think? Does anyone have a WAG on how much extra time investment there is for every toon you add to a multibox team?

Thanks in advance.
