Lately on some bad weather servers I started to get cold a lot and it took over half an hour to warm up again. Even with 4 campfires around me it takes wayyyyy to long to warm up and get rid of a shaking ironsight.
Same goes for cooling down from overheating. It took me over 15 minutes to cool down from overheating even though I was completely submerged in a pond, rolling in water, lieing in water, crouching through water etc. - Tried everything except swimming because afraid to lose gear that way. Even when I took my characters clothes off it took too long. At this time of year the water should be freezing and going into a pond should cool a person down instantly. Even if the water was warm like in the Caribbean it should be refreshing right away. People don't have time to waste 15-30 minutes for this sh#t, especially game breaking when running in a group.
