I hope they make challenges for multiplayer with bots (PVB) and for campaign (PVE) play throughs. PVP should not be the only way to complete challenges that unlock game rewards. And completing PVP challenges should not have any advantage over completing PVB, or PVE challenges either.
PvB will probably fall under PvE challenges, similar to how it is in MCC I’d imagine. If they pretty much copy and paste that sort of setup, with PvP, PvE, and Seasonal challenges, it should be fine, I don’t see any reason why they would even want to switch that part of the game up. As for right now, this is only a flight, and I’m sure they’ll include other ways to unlock rewards. The only issue I’ve got is that nobody seems to care about any of the objective modes right now, but then again that’s present in like every objective based game ever.
