In my opinion, it is the high segment/mileage but relatively low spend flyers getting screwed over the most. With the new program there is 0 incentive to fly more than 30 flights. Also, on upgrade lists it is far more common to find yourself lower now to someone who flys only a few flights per year but have a crazy amount of LPs via cc spend, BAAH, etc. I am at 94 segments for the year and only 150k LPs (130k from flights).
