How will you survive when your addons break during the changeover?
One of them will break. It will most likely be when either the initial patch launches, but might be when MOP is released. It will be the addon you consider most important **.
When do you want to learn how to live without addons? Now, when you have time? Or later when you are trying to level, your opposition is getting all the sales, and you can barely login?
You could practice living without them right now.
You could hop onto Beta (or PTR), and let your addon authors know of your joy or otherwise. You could get involved in fixing or testing them.
You could be a small time supplier using the remote auction house. Note that you are limited to the number of auctions you can have up; and it is incredibly easy to use up all of your remote AH slots selling multiples of glyphs.
** Confirmation bias will back me up. Those with important broken addons will find this post come MoP; those without errors won't even remember it.
