Based on the search results, it is unclear what exactly happened to Warzone ranked. However, there have been some changes made to the game mode. According to, the latest game update includes an impactful change to Warzones Ranked Play, which is the removal of the redeploy flare field upgrade from the competitive mode. This change was made because the upgrade was deemed too powerful. On the other hand, reports that Warzone players are furious over "huge L" ranked play changes in Season 6, but it is unclear what those changes are. Meanwhile, explains that ranked play was down at the start of season six simply because it wasnt re-enabled yet. This is nothing new as something similar has happened in each of the past couple of seasons in MW2. Therefore, it seems that Warzone ranked is still available, but there have been some changes made to the game mode.
