A lot of shows do this. Bring in a new character midway through the run, so half the episodes have to focus on that said character as if to compensate for their absence earlier.
DS9 even introduced a new character in the last season and focused multiple episodes on her!
More than one.
Allot of stories began to focus on Vic. too.
Plus, much like Voyager there was one main character that got pushed into the background until they were almost non-existant-Jake Sisko.
