If its achieving the same results as the previous system with #1 places on the two leaderboards, then whats the point in it? It just appears that it creates a bigger gap between first place which is the only place with any significance and the rest of the places, as perfectly demonstrated by Sarah who already has more than a 3000 point difference on the closest person to her on the rankings, correct me if I'm wrong but the difference between #1 and #2 on the previous system was not as vast as it is now.
I don't see this system as being encouraging to new sparrers or those not as well known, sure enough you can't lose your points but their spar stats are still affected and they'll still be as hesitant as before to spar. How are they supposed to get any sort of respectable ranking once the season has begun, or if they don't have enough time to dedicate to sparring as others do?
This system for a few months will just give the illusion that more players are actively sparring, but after a few months the novelty will just ware off and they'll realize that they have even less chance of getting a dignify rank.
