Babylon 5 was one of the first series to have a finite five year arch outlined before the premier of the first episode.
For better or for worse, over the course of Babylon 5's run, we know the comings and goings of certain actors as well as budget issues led to the overall story of some characters to change. JMS himself has addressed some of these changes in various interviews or posts.
I think it fun to have a thread dedicated to thinking up all those what ifs that either we outright know about, can infer from various bits of information throughout the series or some things that felt like a foregone conclusion that JMS himself never seemed to recognize.
