I'm somewhat surprised and shocked! Having just read that tier (re-!)qualifications will move up 5k resp 10k I have to say:
No, it's not acceptable to move tiers that easily from one barrier to another! This is a 20% increase, but what's the add-on as a customer? Me, being company-wise forced to travel strictly in Y [although relatively frequently] will strike the new regulation quite harsh. Emirates should keep in mind that: Every little helps.
Anyhow, while I have been able to "easily" maintain my status in recent years, I'm less optimistic for my future. Maybe, Emirates has really lost trust/relationship in/to those customers that brought up the airline in the past. As it seems to me, they try to establish another (more than daunting) LH/BA/AF-style system, which has lost me (except the case of lacking opportunities) as a customer already. However, if this might be the case, myself might better change to a similar ...... system offered by a European carrier.
Discussions about additional - even more - exciting membership levels are fine with me, but one should also keep in mind those customers, who made the business growing...

Simply disappointed!
