Now that the game has been out for going on 2 months (MP that is), I and other players are starting to hit BP rank 100 without the use of any boosts. A number of issues if left unchanged are going to quickly become problematic.
Challenge swaps need to be still earnable past rank 100. I’m sitting on a small pile of them, but knowing that there is another 5 months of this season left, and assuming no repeats of “Ultimate Challenge” rewards, players are going to quickly burn through them before the season ends.
The ultimate challenge really should be a completely separate item to work towards. After hitting BP 100, and no longer needing XP, it immediately just turns into a LONG grind just to unlock a minor cosmetic. Instead, the Ultimate Challenge should just be a multi-step challenge, that you can start working towards immediately. Something like: Daily, Weekly, and Ultimate. That way for players that aren’t interested in XP, they can more quickly earn the weekly Ultimate reward.
