If graal wants like Streak, have something like win ratio like comyt said OR have last 100 spar win rate. So it doesn’t discourage players from losing, but rather shows how you performed in last 100 spars. Same with kill/bk.
Ex. If you won last 100 spars, your rate is 100.
Ex2. If you won last 80 spars but lost 20, your rate is 80.
Etc. high streak players are refusing to spar cause they dont wanna lose out on their 60+ streaks..
