I just made the same decision to abandon ae. This one hurts as I was saving for Europe 1 in business. A devaluation of 25%. That shouldnt be. Adjust by 5000 points (5% max) every year perhaps, but this makes planning impossible.

More broadly shows the value of a reliable currency/partner. It is somewhat like phoning your credit card company and telling them the 1000$ you owe them is now just $750. It is somewhat like China devaluating its currency and you holding it. I could see a case for regulation.
