I like online trophies and would like to have podiums related trophies and podium tracking stats as well (not that top 5 nonsense). and yeah, they need to rework XP grind. Pure cancer atm.
I mean, I do like the idea of a trophy based on wins/poles - especially with how GTS used real-world stats from Formula One drivers like Senna and Schumacher - but not when there's the inclusion of ranked matchmaking, which I do support. (Unlike a certain population of online Call of Duty players...) Perhaps a way to have both ranked matchmaking and a trophy based on wins/poles, there should be "seasons" that begin with a ranking reset, rather than how GTS feels like one massive "season," y'know? And these "seasons" could correspond to each stage of the FIAGTC - or, at the longest, the start of each FIAGTC season - and this would be on top of additional, "side-championships" that may offer more interesting rulesets and regulations.
I believe Pokemon GO's competitive scene does something similar, where there's a ranking reset at the start of every season. Meanwhile, the mainline Pokemon games have a different ranking for each tournament that's hosted online. But I also get the interest in a more "unified" ranking stat, like in GTS, so I'm not 100% sure of what to do, though I do think seasonal resets would be best.
In fact, when viewing one's profile, I'd keep SR as both something that stays between seasons and you can view on a profile, whereas DR would not be listed, as your DR would be reset each season, and instead, you'd see a graphic similar to a trophy case, where you immediately can see a driver's total P1/P2/P3 finishes as well as poles, rather than needing to navigate to a separate menu within their profile. You could even select the icon for each of these four items, and you could get a breakdown of which races they obtained them, complete with information like if it was part of a championship, and if so, where in the championship it was obtained. (E.g. stage 2 round 5, or whatever.)
