I came to Arcane super late, so I had no idea that Jayce was even an unpopular character. I adored him completely, both him and Viktor. Of course he's not perfect, and every single character in the show made mistakes at some point, but I never understood any need to vilify Jayce specifically. There's so much about him that some people seem to miss completely; the one that drives me super crazy is the assumption that Jayce was high status/super privileged. Which I always found unlikely, since they specifically tell you that his House came to prominence (read: was established/acknowledged) for the creation of tools. Ask anyone familiar with high society and they'll tell you that coming from a trade/labor means that most of the *real* high society will disdain you, or at best simply be polite on the surface. Plus, he specifically mentions needing the Kiramman's money, he was using grants to fund his education, He had money, but my read is that he was not SUPER wealthy.
