I am one of those customers who always bought B fares on TPAC trips. First of all the pricing difference was negligible, sometimes just a couple of hundred dollars ( or yen equivalent ), it afforded me a possible mileage upgrade, but in any case I collected 150% EQM. Since it seems that they are taking that away, it will be the final nail in the coffin for me. UA still offers the 150% as does CO, who will join *A. On CO though the PE mileage bonus will drop to 125% eff. Mar 1. That is the same as on SM and WP might follow quickly as well. The EQM is of much more value. I think.
