idk, the main part of the electrum gained is selling cards won against FGs
Doubling the post-game electrum award while not doing anything to spin chances/card values would actually put both gold and platinum above FG in total money over time (and IIRC it would put silver not very far away from top tier FG decks, but my numbers aren't in front of me). It would pretty much do a whole lot of nothing for unupped people though.
If this happened, I don't think I'd be the only one to spend the day in plat with 500 HP EM decks hoping for an epic screenshot of beating first place.
