Like anything in life some people like things that others hate. There are certainly worse jobs in aviation, and there are better as well. Dubai is what it is, you either learn to live with it or become a bitter unhappy expat.
No one can tell you wether you are going to be one of the ones that like it here or one of the ones that don't. Like any expat job you really won't know until you come here and live it for a few years. There are guys that have been here 6 months and hate it, there are guys that have been here 10+ years and still like it. All depends on you and your family really. EK can change the situation for the worse by messing with rosters and pay etc, but you just have to move on once you have reached your limit. That is a different point for everyone. It ain't all roses, but it sure isn't as bad as some would have you believe either.
If your family is on the adventurous side and you don't like where you work now, then its worth the try and see what you think IMHO.
