Re: Rank Reset
@superlanky
Between Splits 1 and 2, Respawn have implemented what they're calling a soft reset. This means that, at the start of Split 2, players saw their ranked positions reset by 1.5 tiers down.
Those in Gold II were knocked down to Silver IV, Platinum IV players were reset to Silver II, whoever managed to reach Apex Predator started again at Platinum II, and so on.
