Nah, it's just a badly worded title. From my understanding of the devstream yesterday, Chemistry is separate from Hex rep, and is more in line with the standard romance heart system you'd see in something like Stardew (individual favor per protoframe). They haven't said if it has a daily cap or if it's just very grindy, just that it'd take a while to max out (and that you can redo stuff at certain points if you're unhappy with how things are going).
Oooh, that sounds a lot more interesting, thank you! Maybe my Drifter will manage to not be sad and alone this New Year's after all! And I'm totally not projecting!
Thanks as well for reminding me that Dev Streams are a major part of the canon! Been a while since I dove this deep into Warframe.
