Opened 15 skin crates thus far. First 14 are all commons, 6 dupes. Then the 15th is Night.
The thing about skins crates is that they are all RNG, no pity system or anything for people who open 100 common dupes or anything, which is disheartening compared to hero crate systems (tiered crates, guaranteed 5*, etc). So I could easily be one of you who got 15 green dupes and get rolled over by those who got good skins.
I believe this can be relieved either by raising the duplicate skin dust to yield, or just fill up a meter for rare/legendary skins whenever you open a crate to build towards a good skin.
There’s also two ‘common’ heroes that pop up way too frequently in my crates for me like your Surge, Scum (for 3*) and Heckler (5*, no complains).
