Yes, the system is dumb. It works fine if you have one char, or maybe two, but if you are playing and (lfr) raiding four or more chars a week doing dailies on all of them is completely out of the question. It was perfectly possible to gear all 10 classes before mop, right now this seems quit impossible.
But if you have read the developers interviews, then you probably have noticed that they are aware of this problem and working on a solution. They wanted to make sure you always have something to do on your main, but it is a complete overkill if you have a bunch of alts.
