Just a thought on that RNG with crates, add a guaranteed reward if someone opens enough crates, Say you open 30 crates and dont get coveralls, then you will automatically get it. This system was used in a MMO RPG game i played a long time ago for different skins, if you opened enough crates and did not get the goodies most were after, you would get it after a certain amount of openings... Just a nice thought for those who spend a huge amount of money and not getting anything...
