With the arrival of the winter map, I am of the opinion they need to add climate effects to player characters. People running round in the snow and ice barefoot and in underwear doesn't make any sense. Bring back in world clothing spawns to allow for proper dressing for the climate or terrain.
If we are going to have a variety of maps spawning a number of different climates, allow each map to have some sort of environmental effect on the player.
An easy example are the previously mentioned "naked" people on the new map. IF you are not properly clothed allow for an weather affect that impacts player movement if they do not have the appropriate footwear. If they do not bundle up increase weapon sway from shivering due to being cold.
Use your imagination and similar things can be done on the other maps.
