I saw bunch of people on here last week saying they couldn't finish their Battle Pass. First of all, It's alright because last battle pass was hideous.

Personally I was able to finish it 2 weeks before the act ended. There's no guarantee you'd be playing next month or the month after, for n number of reasons your grind can be cut short so why waste your money?

Just play everyday finish daily and weekly missions and once you've completed the battle pass then buy it and boom you'd have all the skins and the knife. XP boost is a scam anyway.
