Do tank skins drop more often from loot boxes, or is it just my bad luck? Is it some kind of conspiracy because fewer people want to play as a tank?

The thing is, personally, most of the skins I get from loot boxes are tank skins, and I don't like playing that role. I have a huge number of Reinhardt skins, as well as skins for other tank heroes, and... I don't play them because I don't enjoy that role! Sometimes it feels like a conspiracy to get you to play tank by giving you skins for it, because if that's not it, then I must have really bad luck.
