+1 to this suggestion and have my beans as well. If this was implemented it will help us to not freeze to death.
Please, if we pissed off mother nature we are sorry and would like the temps to regulate back to normal.
-1 Keep it the way it is imo. No need removing them. At least lower the spawn rate but I don't think these weapons should be removed from traders either. And also, I don't find this boring at all and trust me there's a lot more shit in the game that is more immersion breaking than the hip firing LMG.
To name a few:
Being able to carry a full size pig in a sack
This list can go on and on but I really don't feel like making a spread sheet. Who cares if a 20 man squad rolls up with .308 caliber weapons. They just came prepared I would assume .
