I'd spar more if the old leaderboard was still being used. The current leaderboard is pointless, just shows who plays the most/ who is the biggest no life. The old leaderboard showed more skill and doesn't require you to sit on graal for excessive hours to be in the top 5-10. Rewards would also encourage me to spar actively and so would a leaderboard in which the top 10 qualified you into being registered into a single spar tournament. Also a spar lag cap of 200-250ms (depending on the time of day) would make sparring more enjoyable.
