I still think people look at this whole ARMs debacle way too deeply and deem **** as "obvious".
Over 15 million copies of Smash Ultimate have sold, and I'd wager only a fraction of those players give a damn about speculating who the next character is.
Honestly, I do think Spring Man would take the average player by shock since, "He's an Assist Trophy", that kind of **** has never happened before in the series history, being promoted to playable from Assist in the same game.
Is it "boring", I mean, sure, I guess, but 'obvious'? Hell no, Springman has a mountain that few have climbed in his path, one that no one's ever vaulted in the same game.
tl;dr: Y'all complaining about Springman being lame cause he's obvious is silly.
