Below we can see the results of the All Star game since 2010. Until then, All Star was much more similar to a real game - which is what most fans were asking for during the last few years. The changes to the teams are primarily made to create some kind of rivalry again (for fans not to watch a random training of best basketball players).
Players are aware of this now, too, there is only a minority of fans who like watching two teams who could not care less.
And the numbers speak for themselves, only last two games were crazy high scoring. Up to that point, 300 total was a golden standart, that was a pretty good balance between entertainment and real basketball game.
If they are about to go back to the right direction, total will follow :) Even with much more 3pt shots taken nowadays, it is reasonable to expect total to drop significantly and 300-325 points is my bet.
