It's actually true : If you want a command you will have to go on a Hong Kong base, since you won't have the seniority for a pax cmd for at least 20 years in Europe. The freighter is an alternative, but note the significant difference in pay, conditions and, especially, rostering/ days off etc.
If you decide on a base, be aware of major changes regarding taxation end of this year. CX will deduct local (e.g. British) tax direct from you !
