I see your point now I suppose. Yeah imo the Battlepass is there to encourage play in the respective BP period, that's the point and I think that especially in the case of Battlepasses the items shkuld become available by alternate methods, permanently after a specified amount of time passed. Though I admit I sort of expected to start rolling out Series 1 rewards into the Crystal vendor when Series 3 came out. Thats 4 months of unavailability but now its like a year. I don't vibe with that.
I can't see it as coercing however. Or maybe I don't because I don't hate pvp in the first place.
That said, the numbers about matches played for Rank 25 are off. It's significantly less.
It's essentially doing a daily CC and still losing for three months, which takes no more than 10min. You accelerate the process with each win and each subsequent match played that day, which naturally piles up the more you play the mode for itself and practice.
