Actually, the lack of stratification by fare class seems to have the opposite effect.

In the current scheme the more expensive fare classes in eco / prem eco have status earning that is probably too generous. Under the new scheme they get dragged down and are not that lucrative.

If you were on the cheap eco fares you might see a boost but it will be tough to qualify given the FTL / SEN points thresholds.

On the other hand the current scheme is very stingy for the cheaper business fare classes. Under the new scheme they get boosted up.

Like you said, winners and losers. But I don't think the new scheme is all that great if you are only flying eco / prem eco.
