When will we get a villain as the final boss again?
Ghetsis was fucking amazing for a final boss. His team actually fucking challenged you, plus unlike every other villain he actually had a full fucking team. He actually felt climactic, and served a purpose in the story.
Champions, mostly, don't serve much of that. They're just there to say "ok you're the big boy now" or something.
I just want something like that, a villain as the final boss (maybe they're the champion), would be entertaining.
