JAL announces change to elite extra checked baggage allowance from April 1

Japan Airlines is unifying its checked baggage rules from April 1 on international flights. All flights will be under the new piece system. Now JAL has announced the updated elite benefits under the new baggage rules.

JGC/JMB Diamond/JGC Premier/JGC Sapphire:
Weigh System: 20kg extra -> 20 kg extra (i.e. no change)
Piece System (in Y): 2x23kg extra (i.e. total of 4x23kg) -> 1x32kg extra (i.e. total of 1x32kg and 2x23kg)
Piece System (in C/F): 2x32kg extra (i.e. total of 4x32kg) -> 1x32kg extra (i.e. total of 4x32kg)

JMB Crystal (no change):
Weigh System: 10kg
Piece System: 1 piece extra (23kg per piece in Y and 32 kg per piece in C/F)

Basically it doesn't affect you if you are flying C/F. But you gain a bigger allowance for 1 piece but lose an extra piece when you fly in Y.

I have mixed feelings about this change. On one hand I get one 32kg piece if I am flying in Y but on the other hand, now I only have 3 pieces (1x32kg + 2x23kg) :(
