Personally, I’ve finished all the weeklies and the capstone challenge, and now I’m just grinding out games. I want to say I’m playing for fun - but I’m not.
20 games to go up 1 level is pretty damn slow. Add in a second fixed, repeating daily for 50 XP to “Win a PvP match”. That way, if I win a game, I’ll get 100 XP, whereas a loss would only give me 50. Incentivise me to win, because right now, I’m only going for kills - which is no doubt having a negative impact on my teammates who still have challenges for winning games.
