One problem I have with force slam being done with Bind is that it makes it a 'dark side' power- one that also requires tree mastery. With a fairly small XP investment a character can start using Move to do force slam on most opponents.
Going back to basics, Move can be used to do all of the move object and force slam stuff we see in the movies, Clone Wars, Rebels.
Bind can be used to do force crush like Vader, or whatever it is Luke does to the Gamorean guards in Jabba's palace.
