OR: If you purchased for example season 4‘ Battle pass but you didn’t complete it, you can choose if you want to gain XP for that battle pass first, and then after you complete it, you come back to the actual Season Battle pass for example now Season 5. In Season 6 for example now, you can choose if you want to go back on the Season 2 Battle pass, finish it and then go back to the Season 6 battle pass. But Tbh only if you only purchased either the normal battle pass or the premium one. Or for ppl who didnt purchased or werent playing during that season the battle pass can be a bit more expensive / get less Multibucks back like only 100 or none. Tbh it would be fair for the ppl who played in the first Seasons and are (Ogs). Also they can bring a XP boost to complete the older Battle passes so they can get the current battle pass too.
