The airline business is all about seniority in general. In other words, gains in seniority are essentially a part of your pay and govern every aspect of your life at a career airline.
Given the way things have been trending you have to ask yourself is this going to be a viable career. Or have you heard ONE person say (again given events as of late) it's likely to be somewhere you'd want to spend the next 20 years of your life given the information you now have at present ? If your plan is try it and bail, remember that you've given up any seniority anywhere else and are kinda 'stuck' offshore far away from opportunities at home. And the 'Las Vegas' syndrome can be a powerful force in clouding future decisions.
The opportunity cost you have by coming to CX is the years you might be gaining seniority somewhere else. The equipment you operate or experience you gain will likely be worth diddly squat in career opportunity terms on a follow on carrier, although they (and bouncing around Asia and some other countries) might be a personal adventure for you.
If you have ulterior motives for coming to Asia you might have a marginally livable life under conditions which have been trending downward (more work for less pay and benefits). There is no rational reason to expect things to get better. You personally have little negotiation position to reverse this, and in HK can have work conditions (and your continued employment) essentially imposed on a whim. There are pie-in-the-sky promises of future 'stuff' but none have any validity until they actually happen; and historically when they have happened have been small opportunities for those at the top of a list on which you are at the bottom. And the history has been long on promises but way short on delivery.
So good luck; you have been well advised of the potential pitfalls of giving it a go.
