Having been in EK for a LAaarge number of years I see the following. If you are under 30 or over 45 with seniority in Command in the ME then EK was a (surprise) reasonably good move.
For the impatient (treated unfairly) or "Grass is Greener" types, always remember that the green grass is due to the large amount of "poop" put on the grass in that field.
Be careful what you wish for, both getting in and getting out.
