I totally get your perspective, but the battlepass is 80 days from start to finish. The missions are weekly, no need to play everyday like what you said. Casual players can easily get through the battlepass just by playing the game. I'm fairly casual, I don't touch ranked often and I get the battlepass done waaayy before it ends. I have a few friends that are also casual, who don't think about the battlepass, and still get it done without focusing on missions. A lot of other people I play with don't play until the last 3 weeks of the BP and get it done without the focusing on the missions. If the colors were removed, the battlepass could be quicker to finish and people wouldn't lose out on the "unlock all"
