1/ I don't think that delayers will even have 1 tie and you know that... Something that has long needed to be fixed but nobody has done anything. I'm not going to defend something because I get advantage out of it.
2/ for the w/l one, the win leaderboard is basically a daily one..
And the losses page will be occupied by noobs lol imagine a group of new sparrers that keep sparring everyday, they will all be on it and probably losses can get a range of 3k-1k by season?? if the 100th person has 1k losses, you won't see the active sparrers' losses on it and I suppose the purpose of it is to see how many losses the active sparrers are getting. Personally I don't get 1k losses per season.
And if you decide to put w-l on the same page, it's impossible.

This is not an arguable thing, the PK and BK leaderboard work just fine so why not implement it to sparring? Every spar leaderboard we've had had flaws.
