Too be fair, he's essentially Sovereign in the sense that he's part of the collective Reaper consciousness but still a separate entity in a way. He's also the FIRST Reaper so he must have some sort of role that makes him a bit different from the usual rank and file Reaper forces. IMO, they should have just scrapped the Catalyst completely and filled the role with Harbinger instead. Ignoring Leviathan and tweaking the dialogue a bit, it would have essentially accomplished the same exact thing without the need to introduce an completely new character at the end.
