Although there are some families who don't celebrate for secular reasons, the majority of the them don't take part in halloween, for religious reasons. Religion plays a key role in most other major holidays such as Christmas, passover, easter, and Yom Kippur, but halloween is not usually associated with religion.

There are several reasons why some people may choose not to celebrate Halloween. Some individuals or religious groups may have beliefs or traditions that conflict with the holiday's origins or practices. Others may simply not enjoy the spooky or costume-focused aspects of the holiday.

Furthermore, Ranked Play in Warzone 2.0 uses a similar ranking system to that in Call of Duty: Modern Warfare II multiplayer (learn more about it here). There are seven standard Skill Divisions, with all players beginning at Bronze I at the start of Season 03 Reloaded.

Everything you have earned on MW2 Multiplayer will be reset. This will not affect your Campaign / Spec Ops progress. Note - There is no easy way to revert your rank to what it was before it was hacked. You can either stick with your modded rank, or reset it.
