I hope that you will consider modifying the heat given off by fireplaces on Sakhal.
Make it so that it warms an entire building like it would in real life. I built a base inside one of those grey steel 'Livonia Warehouses' (the ones with 2 sets of big grey doors, and one small side door). I found it ridiculous and incredibly frustrating that I have to stay within a 2 metre circle of the fireplace in order to receive the heat buff, whereas as in real life, it would raise the entire temperature of the warehouse.
So, what I wanted to suggest was to improve the DayZ fire's heat radiance to heat an entire building, making it habitable like it real life, instead of being forced to sit staring at your screen for x minutes instead of doing 'basey' type things
