There won't be any gameplay challenges in the first Rocket Pass. We intend to add a "Weekly Win Bonus" as part of Progression updates that allows you to level-up faster by winning enough games each week. We are being careful about introducing "challenges" as we don't want to disrupt the competitive balance of Rocket League by encouraging users to hunt down specific stats like Saves or Assists. That said, we are considering safe ways to give players specific goals for future Passes, like playing matches in specific game modes, or achieving shared team objectives.

Will high-level players earn Pass Tiers more slowly because their levels take longer?

Nope! As part of the Progression updates we've mentioned, all levels beyond a certain threshold require the same amount of experience. Level 30 will take just as long as Level 300. So you won’t be at any disadvantage if you’ve played more than someone else.
