Yeah it seems this mechanic is a bit forgotten these days, maybe because the companies are trying to ease their games as much as possible.
The last game I can remember to distribute attribute points is Diablo 2 and I played it 15 years ago :D
It is a good mechanic and brings diversity, when it is combined with talents you could make some awesome builds for the classes.
PS: I remembered a more recent example of an MMO - Neverwinter, they had distribution if I'm not mistaking.
