Well I can see the intention of preventing it from obtaining high level things when you can't yourself but honestly if you have 1 dps class leveled to 60 then you can get the same things that the others can, even the gear. Just can't wear it.

Maybe as long as you have a dps 60 you could do any of the dps, a tank 60 you can do any of the tanks. a gatherer 60 any of the gatherers etc?

I dont like this restriction though, I have gear for ninja even though I didn't level it. Was saving it for a retainer cause I like how it looked.
