Lots and lots of games have them and some people love them. Can't say they would be my top priority but they have fixed several big problems in the last two updates.
* Salaries of the top players reduced a lot.
* Incorrect rookie salaries.
* 5th being better than 4th.
* Big changes in the salary floor to combat tanking.
* Career stats for players.
* Player ads are back (a policy change not a coding one)
The Facebook and achievements stuff wouldn't be my top priority but they have fixed almost everything else that was on my fix list, things remaining for me are:
* GE tweaks make 2/3 zone better and weaken LI
* Remove or weaken the blank lineups
* Improve the median quality of draft picks (not the top ones keep them the same or even rarer)
* Do something about player prices (although they have been low for so long now I almost have forgotten how itused to be)
