This has happened to many 727 Capts who've been excessed too

....however, after the first 777 bid many saw that they could delay their downgrade by bidding 777 FO rather than MD-11 or A300 FO, and later bid the 777 on subsequent excess bids to do just that.

The company's position will most likely be --- if you wanted to delay your training the most you should have bid 727 SO, and then you could have stayed in ANC longer --- but of course, you'd end up in the back of the Purple Slave Ship at a lower pay rate until the next FO vacancy bid or SO excess bid.

...Worth it in terms of pay or QOL?

I don't know --- I think that would be an individual preference.

Bottom line: Yes --- being excessed $uck$!!
