Maybe I am applying my own arbitrary expectation here, but It seems more appropriate to have prime and lesser evils pertain to the launches, campaigns, and expansions. World boss like entities should pertain to seasonal storylines (that way maybe we could have different world bosses at some point?..possibly?). Atleast a consistency can be had where, the campaign, expansions and launches are all furthering the story, while seasons are what I guess could be considered the “small battles that make up the war” kinda thing? Idk, just a thought.
