Honestly the free to play model sucks, but the battle pass progression is terrible every other game did that right at least, you should earn XP for each game, you are gated so hard with the challenges and wtf are XP tokens anyway you waste so much XP if you don’t finish a challenge in the 30 min. Which still ticks out of game.
Yes and no. Pros. Does stop people AFK’ing for XP which is rife on some platforms.
As for slow progression. Season is 166 days long. It’s like day 2-3. Chill!
