That figure of 29,700 Dhs includes an hourly flying pay of 85hrs so no, the basic salary has not changed. In fact in hasn't changed for the last 3 years. It certainly needs to as it is neither competitive in the current market nor is it in any way relevant to the cost of living change in Dubai over those 3 years.
Almost every single positive element of working for Emirates is going in the wrong direction at the moment. Just look at the threads here about max flying hours and lack of annual leave amongst others. There is no indication that any attempts are being made to address and improve any of these issues. Quite the opposite actually.
There are better options out there, even in the this region.
