So, here's the secret to rapid Battle Pass points: play tier 6-7s, especially LTs and fast MTs/TDs. The games are over faster, if you know what you're doing, you're placing top 3 XP consistently and winning more often, and when you get to 100 points you get an extra 15 points. If you spam 15 Type 64 battles in a day, that's 115 points right there. Repeat with 12T, T21, CromB, Rudy/34-85M, and they add up fast. Also, if you have some Tier 8-10s close to the point limit, keep them there, and just hit the point limit once the marathon goes live for easy cheap points.
