Indeed a "nice improvement" (I think now we have been "enhanced" too much already), they always follow their neighbor/competitor moves (at least for bad ones I mean) even without having the same strength and appeal, furthermore they did it without any consideration for higher tier members.
I was still considering free seat selection one of the few remaining bonuses of flying EY, at least when traveling with my family in economy, since now out of CGK to Europe the competition on discounted J fares is becoming tough (QR, TK and WY most of the time are now cheaper) in the future not sure I will fly with them again even for my regular solo trips to Italy.
It is clear they are cutting costs tremendously but with this pace they will also cut customers.
