I think this mechanic is great to get rid of new players. As an advanced player you don't even notice it.
I don't know, maybe snow men as a defence are really great and interesting, and needing some preparation to go into the mountains sounds interesting too, but so far the whole mechanic seems to be an entry barrier for people who randomly find Salem.
But honestly we had this topic like 10 times before and the arguments on both sides are always the same.
A says newbe basher and otherwise boring mechanic
B says there are plenty of tool tips and people should just read
I am group A because I want more players and don't see any added challenge to Salem due to the cold mechanic as it is right now. The moment I wear any clothes on most slots the thermal value doesn't seem to matter anyway which is why I can just ignore that stat completely when I chose my gear. If there was cloth with lower value but more slots and clothes with a higher value and less slots, I'd maybe have to balance out certain clothes against each other in order to take care of the cold. But as it is right now, it doesn't add to ingame depth at all. If there was a need to get higher thermal for certain areas or biomes like Dallane suggested and you really had to max out your thermal for that, then the mechanic would at least become relevant for higher players and maybe less relevant for newbs (the way it should be in my opinion).
Crows are a slow down for farming, which is in my opinion still one of the easiest ways to make masses of money, so that is a little bit of a balancer for the income on different jobs against each other. Even with crows I think farming is the most efficient way to make money.
Some people are so busy learning the tricks of the trade that they never learn the trade.
