Mmm007 I've got also the same problem, EK flies from my country but not from the the city where I live, so I have decided to travel by train, there is no luggage restrictions. I don't think emirates is going to pay for the luggage from any city, just from the ones that they fly to.
Just one more thing: it's not 50 kgs, it's 50 kgs plus hand luggage!!
