Pretty straight forward. Why would you use the name "de_dust2rework" instead of something related to Christmas? dust2_xmas, dust2_xmas2016, etc...

The reason for asking this is, when this map is called up for vote, it shows the option as de_dust2rework. The majority of people who are not familiar with the map will assume it's just some bland rework of a perfectly fine map instead of a Christmas version, which would significantly increase the attraction to vote for it.

I've used various themed versions of Dust2 and Mirage on my pub servers during different points of the year for many years now. They are always a hit. But this has gone almost unplayed due to the fact that hardly anyone knows that it's a dope Christmas version during the map vote.
