Whilst many may agree with your sentiments..........FFS, this topic has been done to death, and, no, it won't be a game changer in the way that you perceive.
The reality is that EK will continue regardless of whether they hire DEC's or not. The management don't care whether the pilots are happy or not with the DEC issue or any other issue for that matter. As long as the a/c go from A to B and back to A, that's all that matters to them.
Boatloads of FO's will not leave thereby crippling the system, and even if they did they would merely offer a sweetner to keep sufficient numbers in Dubai.
Everybody needs to spare themselves the angst that this issue brings up every time because it will make no difference to the final decision that the mis-management make.
