So this is what I was experimenting for a few months now.
I stopped playing it for a good month. Now some think I get the week gifts thing, but I didn’t get it. But, here’s what I got instead.
I feel like my chances of rarer heroes has increased drastically. Odd, but left the game for a month, Alvarez Feature Crate came, had 5 tokens, placed one in, boom. Alvarez. But here’s something even funnier. I had three 3* heroes out of the 3 tokens, and then the last one, boom, Brogan. IDK if it’s intense luck or a loophole, but I had experienced this for a while now.
