Dew collectors are for people trapped on a island with nothing but salt water or maybe a desert. In this situation boiling and filtering water from streams and lakes or rain water, would be the method survivors would use. Just saying it doesn't fit the situation. That being said as a game mechanic, it's not that big a deal, just seems like an unnecessary change to me. In my opinion, making things annoying doesn't make them challenging and it for sure doesn't make them fun.
