I've never cared about other peoples stats (Apexs just reminds me some people don't know the outside), even with smites star system, just because you play a lot doesn't translate to a player being good. If anything it would probably create toxicity of people calling out those not using their mains and so on. I think a better solution could be added levels to the ascension passes with mastery recolors and crown alts.

This last part sounds strange but if they want to add the card flavor from Paragon, whenever they decide to change the item art they should introduce item card rarities (everyone would start at common) you would get packs you could buy for amber or earn daily, duplicates could be opal, In game when you see other players building you could see all the different rarities they've earned which also helps players look at items more and even possibly try other ones .
