RNG and probability. One day you get lucky, most other days you don't.
I got 118 Govou from the cycle on the last 10 drafts, so thats 70 drafts for a "B grade Hero/Icon" for under 200k gems, at least I did not get some other nonsensical, couldn't care less about 118 OVR card.
Still, I prefer drafts with a pity counter that guarantees a pool A after 70 draft cards over store packs that did not guarantee jack....
Even these super expensive big promo packs for 50k gems (or whatever these used to cost), I got the lowest rewards with the accuracy of a Swiss watch 🙃
