Going to a big ME airline is something that should only be done with a solid game plan in mind - set a target, be it, time, $$ or whatever. Reassess it from time to time, but stick to it.
Having been at one for 20+ years and taken what I could from it, it was clearly time to leave (within the last 6 months). It certainly wasn't the airline I joined in 2000, with less opportunity, much lower remuneration (in real terms) and a MUCH higher BS quotient. I could only recommend going to EK/QR/Etihad with a plan, and then only if it was a step up and left you with experience you could market...but a job for life they no longer are.
