“Limited time” game modes that are popular. VL- 7 Contaminated

Completely agree with this. Came especially onto the forum to make this point. So I hope community managers are reading this along and bring this feedback with them back to the table. 

Why would you invest all of the time and make something and them decide to take it away?
I wasn't very impressed with the winter mode, but it did add something. 
Especially very much impressed with Contaminated and the gas. Really adds something to the gameplay. I mean play the map without and you will find it much less fun. 

So I would suggest to get rid of the time limited events when it comes to maps. Just leave an option in the map selection (for people using custom search) where you can choose to play the version with or without the gas/winter elements. 

EDIT: I really don't understand this, especially in a game with such a quick decrease in player count compared to the launch, you would expect developers to leave maximum content and variations (if already developed anyway) to attract the most amount of players. So developers please that this feedback seriously.
