I know in the fandom people didn't like how things felt plain after the Darksigners arc, but personally I think what they needed was an inbetweener. The second and third seasons really did feel extremely distant from each other nothing wrong with that but I always think they did needed an inbetween arc for Season 2 and 3 because of how a lot changed afterward or they needed to explain some stuff like what the hell happened to Ralley and Yusei's original gang? How did New Domino take Goodwin as the bad guy the whole time? Closure for Akiza after Sayer and the Arcadia movement always being a sham, and what ended up happening to Yanagi and Tanner? Honestly I think that is what should have happened before the WGPX arc or inbetween Seasons 2 and 3.
