I'll probably get flamed for this. If you want my opinion, I say if you are tired of your routine in the Pacific, leave Vanuatu and go see the world. Sure, everyone bags on EK - and rightfully so given the changing contracts and mediocre pay. However, if you can get past a lot of the negativity in terms of pay and upgrade time on some fleets, EK COULD be a great experience. You could fly some great equipment and see a lot of the world if those things are important to you - they aren't for some people...
I am not suggesting that EK is a great place at the moment - probably far from it. However, there are some positives and those should be considered. If you want to see the world beyond your island, fly some advanced equipment, don't mind living in a very expensive desert location, then maybe EK is for you. You would have to go back to the RHS from the LHS - I have heard that can be a difficult transition for some.
If you have visited Dubai and you are OK with the change of scenery, I say go for it and hope you get onto one of the quicker-upgrade fleets. I think that I have read that the 777 upgrade is quicker than the A330/A340. However, make sure that you PM many of the EK pilots on these boards and get more opinions - just realize that many of these pilots do nothing but complain...
Good luck and let us know how you do...
