Well all I know is that when I do a player search in the game on my server and see 91 active level 50 black mages over the 35 active level 50 summoners during my prime time then there must be a reason for such a huge gap in these two jobs. SMN needs to be looked at by the devs and seriously tweaked in order to bring the SMN population back up or at some point in time it will become so small that they will be forced to make changes to the job in order to bring players to it.
