On the day of the patch that raises the chance for a cosmetic I was very excited to open the 100 chests I had saved hoping the % chance was reasonable. I had opened 135 chests a few weeks ago, and found the same result. Zero cosmetic items. The funny thing is, I found 2 red items today. I have found 25+ reds since I started playing this game and would gladly trade some of them for a cosmetic. Fatshark, please, raise those %s!!!
Steam says I have 1048 hours in this game. Only two cosmetics ever found. Most of my heroes are +100 or more, and some are +150 in level. Imagine how many commendation chests I have opened. Can my luck really be THAT bad?
EDIT: I have found TWO cosmetic items in 1048 hours of game play. You do the math
