Question about challange rewards.
I'm trying to figure out how reward xp from challanges are determined. I often find myself againt players with double level than me. These matches are quite good and the rewards are quite generous. But every once in a while I'm in a match where I will get only 1xp if I win, and a huge chunk will get deducted if I lose. Happens with opponents both higher or lower level than me. What are these edge cases? I usually ignored challanges with less than 10xp reward, but recently I'm getting way more of these.
