Thallen's spar leadboard remodel should be heavily considered.
As for "lag and walling" being used to acquire high positions on the leaderboard, yeah it happens. You can't blame people that live in foreign countries for lag, it isn't their fault. However, for many of the the non-laggy sparrers, it can be annoying (personally I don't care, as long as they don't purposely abuse it). I only have a problem with two of the laggy sparrers, and those people are Abood and Sarah. Both are stuck-up and snotty, even though the majority of their wins are from constant warping. Also, both constantly go for 'cheap shots' in spar (Hit if other person is talking, afk, etc.). They don't irritate me because their lag, just their personalities.
Anyways, sparring is dead. If you think so, you should delete graal off your device and stop using this forum.
