I wish i could see mercy count, i have pulled dozens of voids and had 2 legos in total, one of whom was jingwon.
When i see clan mates with half a dozen void legos i wonder what i am doing wrong
I keep track of mine in discord. Makes it easier to see how close I am.
That said - it's just luck of the draw. Personally I have three void legos (cruetraxa, raglin, and angry), which I expect is probably par for the course.
