The thought is that players will realize what they're getting from Blueprints rather than "shock mechanics" of plunder boxes, which have been dubious. In May, United States representative Josh Hawley proposed new enactment that would boycott pay-to-win mechanics and prohibit organizations from selling plunder boxes to kids. Psyonix's change to Blueprints is one approach to deal with the contention. Adding a plunder box "X-beam scanner" to Rocket League Credits Counter-Strike: Global Offensive in for French players is another way.
Anyway, in Rocket League, Crates will stay until the December update, and when it does, Rocket League keys will be changed over into Credits. Boxes, as well, will be changed over into Blueprints "of a similar arrangement," Pysonix said.
Before Crates go, however, there's one final Crate in Rocket League: the Vindicator Crate, which "will highlight the new Sentinel Battle-Car and Neuro-Agitator Goal Explosion." More subtleties on the Blueprint change cycle will come "in the following scarcely any months."
Psyonix additionally reported changes to the Trade-In Rocket League Credits framework when Blueprints are added to Rocket League. It'll "handicap the capacity to utilize paid substance" in the Trade-In framework. Anything from Blueprints, the Item Shop, or Crates won't have the option to be exchanged once the update goes live. Free post-game drops will at present have the option to be exchanged.
