Another aspect on basing vs no basing is - Do they want you to bring your money out of the UAE and spend them elsewhere? I think not. At the moment they could prob up your pay to "sort out" recruitment problems, knowing that if you make more, you will spend more... In DXB that is. Its all a great circle - they pay you, you spend it on their house, schools, restaurants, shops etc etc. Basing will be the ABSOLUTE last resort for them if you ask me.
Good luck to all!
