Thanks for the tag!
I can definitely see where both sides of the discussion are coming from. Challenges that encourage social or multiplayer activities can help players explore different parts of the game, but I also understand the frustration from players who primarily enjoy skating solo and feel locked out of completing certain challenge sets.
I think the suggestion of separating solo and multiplayer objectives, or providing alternative ways to complete some challenge tracks, is interesting feedback. While I can't make any promises regarding future changes, I've been following the conversation and will make sure the team's aware of the feedback being shared here.
Appreciate everyone keeping the discussion constructive and taking the time to explain their perspectives.
