The "Experience" and "Bounty Points" categories have been removed from the weekly competitions and will be replaced by other categories soon.
The reason for the removal is because whoever has the most levels, usually has the most experience as well. Same goes for bounty points, whoever has the most kills usually has the most bounty points.
In case that's the case with CW points and CW's played as well, "Most CW's Played" will also be replaced by something else.
