I didn't like the demotion of Geordi either. In ST V and VI, both Spock and Kirk were captains so why is having 2 captains an issue? I didn't see why it was necessary to even make that point come up. Geordi's rank had nothing to do with what was going on. Why did DRG III even need to make an issue of it?
Then there is Spock saying Scotty is dead rather than lost. Lone Magpie made a point of saying that the editors wanted Scotty's fate unclear. Also, RBOE ended with Tomalek stepping down from the proconsul position, now he takes it back only to step in agian.
Why was it necessary to undo or change these points from previous books?
