The removal of night credits mean that pilots effectively do another one to two 4-5 day trips a roster for free.
More mis-information!! The MGH has been reduced to 145 hours with planning at 155 hours to account for this. That means that you will not be spending ANY more time at work than you currently would under the WD for the range of flying suggested of this aircraft (a mix of current or similar 330, 747 and 380 trips).
The other mis-truth being sprouted at the moment is this gem that without overtime and night credits there will be no incentive (or compensation) to bid for ULR flying. What BS!! Its called density. The incentive is you can do more of your required hours flying in less amount of days = MORE DAYS OFF AT HOME (some people may even call this
"lifestyle" 
. Pretty much all SH folks and anyone flying ULR for any of our major competitors understand this concept. (Caveat - Clearly there are some variables here like route frequency and total time away from base but these occur with or without overtime and is where MDC protection kicks in)
