Sounds like the bidline system has changed.
At the risk of repetition ... yes indeed, whether that's for good or bad depends on your POV.
If you (or anybody else for that matter) starts hearing tales from someone on the joys of Bidline ask them when they last worked as BA Flight Crew. If it's longer ago than the end of '14 than frankly you're probably better off politely ignoring the input.
(but sorry, can't help with the roster but FWIW a final roster in isolation, in itself, might not tell the whole story, you'd need to see the road travelled.....).
