It is very frustrating with the rain in the game. So far no matter what I have on I have the dark blue temp within 2 to 3 mins. I have used the raincoats and as much as they don't get wet I still end up in the dark blue and I have been running with 5/6 of the stamina bar available. It would be good before you implement something like the temp stat that there is proper protection. Raincoats that work, other items that only get you into the light blue if the damage is worn or better and items that offer no protection. Light blue should make you burn through calories Dark blue calories and health.
